Another day, another format war rumor. Business Week has a lengthy writeup on the possibility of lone dual-format holdout Warner Brothers switching to Blu-ray exclusively, and how it could affect the outcome of the long-running feud between high-definition disc formats HD DVD and Blu-ray. The rumor gets its seed from vice-chairman of Lionsgate Michael Burns, who claims that Warner will be turning blue soon. With Warner on their side, the Blu-ray studios would hold a 70% market share for the DVD market. Of course, if Warner shifts red, then the studio market will again be split into two equal halves, and consumers are left to wait and see if one format can outsell, outspend, or outlast the other until only one format remains. The stakes are so high that top execs from both camps are banging down Warner's door with personal meetings -- and possibly even truckloads of cash -- to get Warner to turn to their side. One thing you can be sure of is that Warner is going to be keeping an extra close eye on the dual-format release of Harry Potter next week for guidance.

Sony is said to have yet another PlayStation 3 firmware update ready for download before Christmas, with the gift for movie-loving gamers being Profile 1.1 compatibility for Blu-ray Discs. Competing format HD DVD has had support for Profile 1.1 features such as picture-in-picture, secondary audio, and local storage since its inception, while in the Blu-ray spec they were optional. There aren't any Profile 1.1 Blu-ray titles on the market yet, and only a single 1.1-compatible player for sale from Panasonic, so this is really about having one more bullet point on a box for fanboys to argue about. The only major HD DVD feature that becomes required in Profile 2.0 is Internet connectivity, so downloadable content will still be optional for some 1.1-compatible BD players -- but not the PS3 with its built-in Ethernet jack. Considering the PS3 is still one of the cheapest and most widely-owned Blu-ray players, and Sony continues to improve its capabilities via firmware updates, PS3 fans and Blu-ray Disc aficionados have that much more ammo to use in the never-ending format war.

We're not exactly sure what to make of this, but LG's BH200 combo HD DVD / Blu-ray player is currently listed on Circuit City's website for $799, which is about $100 cheaper than anywhere else and $200 cheaper than a certain blue competitor. It might well be a typo, of course (and probably is), but between Big Red's pre-Black Friday price-chopping and our own fervent hopes for format peace, we're going to keep on dreaming until we hear otherwise.

Update: Yep, too good to be true -- it's back up to $999 now.

It just wouldn't be a proper format war without a rebuttal from the opposing side about this week's announcement that Blu-ray has sold over a million discs. The HD DVD PR machine scrambled to life to point out that they, too, are so close to that magic million, with their own sales numbers showing 998,000 units sold, up from the 937,500 reported by Home Media Research. The HD camp also points out that -- not including the PS3 or Xbox add-ons -- standalone next-gen DVD hardware is selling 4-to-1 in favor of HD DVD this month, and content sales numbers are very close week-to-week between the two formats. Meanwhile, the average consumer sits on the sidelines waiting for a winner to emerge from the fight -- that is, if they can even spell it.

Once the realm of mighty giants with huge pocketbooks, burning a dual-layer Blu-ray (or HD DVD) disc might be yours at ten times normal speed starting in 2008, when Japanese firm Nichia Corp. will start production on a higher-powered laser diode for use in recorders. The diode emits pulsed light at a higher output than current diodes, and is stable enough for 1,000 hours of operation, which we estimate should net you around 5,000 two-hour burns... of data, of course! It will also allow for 2x burning of up to four layers. We're still waiting for word on how fast it will burn those ten-layered discs.
