According to this excerpt from the New York Times, HD-DVD is as good as dead:
Variety is reporting that the last two major studios backing HD DVD — NBC Universal and Paramount — are opening the door for a switch to Blu-ray....(Earlier) Warner Brothers, which had been issuing movies in both formats, decided to go exclusively with Sony’s Blu-ray format....So what appeared to be a stalemate may, with one relatively small move by Warner, now turn out to be a quick victory for Sony.
It's the death of a salesman for Toshiba and Microsoft.
So that's that. This confirms the "format war" never was going to be about PS3 or Xbox 360 sales, or even superior consumer utility -- it was about which format had more media. And now that format is Blu-Ray -- and it's not even close.
