" The window of opportunity for high-definition DVD could be missed if format confusion continues to linger," said Warner chairman Barry Meyer, suggesting that this move will end the format war. We are a bit sad about this, given our current love of Warner' s HD DVDs over their identical Blu-ray titles. And there' s still a lot of momentum on the HD DVD side, with Paramount, DreamWorks and Universal exclusivity. But this is a massive blow for sure.
