Halo 2 at the moment until the world gets to see the mighty greatness of Halo 3.

Two, most are waiting for the Wiiiii

HD-DVD drive of course

Halo 2 of course

Halo 2 of course, until the next Halo game comes out that is!

I want a Nokia Olut!

It would seem that way until you realise that the human eyeball is vastly more complex than any other electronic imaging system deployed today.

As mentioned previously I'm an electronics engineer in my day job and I previously worked on the design and charaterisation of such systems. Outside of work I also have more than a passing interest in neuroscience, and enjoy reading and researching in this area. In short I think that as an engineer, I can learn a lot from examining and studying what works in the wiring of human beings. Evolution is a great designer!

But I digress, to contrast a human eyeball and a lens system with an electronic CCD / CMOS sensor array. The lens and optical systems are relatively similar, well, except for the fantastic liquid lens in the eyeball. What are very different are the image sensors, i.e. the CCD and retina. The CCD, due to it being a solid state electronics device is highly uniform and regular, with an equal number of sensor elements per unit area. In contrast the retina is quite diverse in the distribution of rods ( light sensitive but no colour ) and cones ( colour sensitive but lacking in light sensitivity ). If all our brains did was read out the image from the retina it would look like an unintelligible mess. We're forgetting the amazingness of the human brain though. This processes the output from the optic nerve and in engineering parlance, applies a sophiticated series of filters and interpolative algorithms to produce the 'image' that we 'see'.

Some interesting work is being done in this area with regards to image processing but I cannot forsee a drastic change in the actual electronic imaging 'chain' for the forseeable future.

I completely agree with the previous poster.

The resolution of the sensor array is total irrelevant unless you have the optics in the imaging system to back it up.

I'm an electronics engineer and a couple of years ago worked for a large mobile phone company. The main array of my work was imaging systems in mobile handsets.

When evaulating sensors from various suppliers ( Toshiba and ST in my case ) I often received the sensors with coated glass optics. Despite the low resolutions ( 640 x 480 ) the images were great. However when the same sensors were placed in a system with uncoated single element plastic optics the images weren't so hot and abberations prevailed. We actually found that using an anti-IR coating on the lenses helped a lot, sadly our recommendations were ignored.

In short, give me a 640x480 sensor with decent focusable optics over a fixed focus 2MP sensor anyday!
