Warner was the last major studio left that was releasing titles on both formats but, Blu Ray has won the bidding war and Warner has no joined the likes of Disney and will only be releasing their movies on Blu Ray starting June 2008. This comes just a month after HD had its big Black Friday sale of 169 dollar HD DVD players... and even with that sale, Blu Ray costing way more, outsold HD DVD players 2 to 1. And for the 52nd week in a row, Blu-ray Disc software has outsold HD-DVD software. For the last week of 2007, the margin was reportedly 61 to 39 according to Neilsen/VideoScan. This means Blu-ray software sales have outpaced those of HD-DVD for the entire calendar year of 2007, with no signs of slowing down.
Blu-ray now has 70% exclusive access to Hollywood studio content. Expect this Blu Ray vs HD DVD war to come to an end this year, with Blu Ray coming out on top. Universal and Paramount are HD only, but expect them to make a jump at some point. Either way, I am good to go, I own both HD DVD and Blu Ray players. And personally, I side with Blu Ray.
