I don't think them winning the Blu-ray war really matters because it seems like most consumers are perfectly content with their DVDs. Blur-ray will end up being like Laser-Disc and Super Audio CDs, by which I mean they will be niche products for technophiles and for the rich but they just won't catch on with the mainstream.
Hell, most people don't even have HD tvs. They either can't afford it, or are content with what they have. There's absolutely no point in having a Blur-ray player (or even PS3 for that matter) if you just have a Standard defniiton TV.
