At what cost though?
1tb at 100 x the price of a 1tb SSD?
On current Blu-ray media pricing that's not too far fetched.

I'd love to know where people get the idea that Hollywood is ever going to be interested in selling 4K movies.
That's effectively a master copy of the movie.

That's never going to happen.

Similarly if NTSC & PAL are anything to go by 720p/1080i/1080p is it for a very very long time.

We'll probably see a small retail line in high-end TVs doing upscaling to 2K in the next 5 to 10yrs but that's about as far as this goes I reckon.
Why would they bother?
Far too few are ever going to have the 100"+ TV to make any sense of it.]]>Jul 24th 2010 11:12AMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/Jul 24th 2010 5:42PMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/
You're still kidding yourself if you seriously think Hollywood are going to give away master copies of their films.
I can see no credible reason why they would ever do that.

Regardless, the fact stands that HD as we currently know it is it for a very long time.
The upscaling to 2K I can envisage for a tiny number who need and and the slightly larger number who will kid themselves (or allow themselves to be kidded) that they need it but it's never going to be mass market.

Hardly anyone (relatively speaking) has, or will ever have, a 100"+ TV set in the home and far to few will ever create a true home cinema set-up requiring one.
That alone ensures that not only will 4K be not going mass market but that there is absolutely no serious practical point in going to 4K in the first place.

Why?
They don't even do that now.
They try to pay very strict attention to even screener DVD copies of their films nevermind something like a 4K digital copy.

Seriously guys, as fun your day-dreams for a domestic video market based on a 4K digital copy (who cares what media it comes on) might be there is absolutely no way that is happening - primarily because there will never be any sizeable demand from the mass market.]]>Jul 25th 2010 12:10PMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/Jul 24th 2010 3:00AMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/sony would love to license it to microsoft

Your kidding right?

If Sony licenses this tech to microsoft, no matter the cost, Microsoft would just slap them in the face by stealing the exclusivity by making the devs sign a timed contract..

Sure sony would make alot, but then microsoft not only has the best tech, but also the most money to steal all the devs away from sony..

Brains are a wonderful thing, eh?]]>Jul 24th 2010 4:06AMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/

With the extremely crappy infrastructure of North America, I don't think 4K video can be streamed widely without moderate to heavy quality loss anytime soon (which this thing is probably targeted for). Physical Disks with high densities will still stick around for some time. Look at Blu-ray video, then look at a streamed video from something like Netflix or PSN Video. You're set to notice quality loss.]]>Jul 24th 2010 3:15AMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/Jul 24th 2010 6:25PMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/For example a car motor there has been changes to it ever since it was first invented, but basically its not so different it just got its updates.

The problem is limiting the laser beam so it doesn't continue on. Once they can cap the beam at a certain length then you'll have your light sabre. ]]>Jul 24th 2010 12:36PMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/
The handle of the sabre emits a powerful magnetic field. A magnet with the reflective side is held 3-4ft off of the base of the magnet, reflecting the laser back into the base, where the reflector in the base reflects it back, increasing the power of the beam.]]>Jul 24th 2010 2:10PMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/I think that the light being contained via a magnetic field only works in crappy directors imaginations.]]>Jul 24th 2010 5:05PMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/Jul 24th 2010 3:19AMhttp://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/http://www.engadget.com/2010/07/24/sony-tohoku-university-develop-blue-violet-laser-with-100-watt/

No no! iTunes sells HD movies, full on 720P! HAHAHA. I hate people who buy into the Apple crap of labeling their movies "HD". While by definition 720 is a form of HD, it's shitty HD. The world where we can easily distribute and store lots of movies on a quality level of Blu-Ray is years off. Then you're going to have to add in 3D, and eventually 4K and that time is even more years off.

Everybody knows the world will eventually go streaming/downloading, but everybody has been saying that for years. We aren't able to do it efficiently yet, and we won't be able to do it for a long long time. UltraViolet seems to be the most promising upcoming service towards this goal, but we'll see how it pans out.

Lets not forget that most archivists, secretary of state office and records management associations do not recognize Hard Drives as permanent long term storage. They do however consider microfilm (yes you heard it correctly) and optical disc based storage solutions as long term. If you send your secretary of states office a hard drive to store they will send it back immediately.

Most of the world still uses optical disc. You do know that multi millions of blank optical discs are sold every year?
So many discs are in the wild, from CDs to BDs that we will always in our lifetime be able to purchase a drive to read these items. There will always be an need for retrieval of data from these shiny discs.
