I think that's a false choice though. Everything had been trending Blu-Ray LONG before the PS3 came out, and it's not like Blu-Ray is exactly dominating DVD at the moment, it's what, 10% of the market at best if I recall? Let's say the PS3 hadn't had Blu-Ray capabilities. It's possible HD-DVD would've held out longer, but do you honestly think it would have won? And do you honestly think Blu-Ray adoption would be THAT significantly less? I don't, I think Sony went for overkill by including Blu-Ray in the PS3, it wasn't necessary and I don't see it being a major factor as to whether or not Blu-Ray becomes adopted by a majority of mainstream audiences like DVD or VHS, it's still got the potential to be a Laserdisc like format (I don't expect it to be one long term, but it's got a few more years before it becomes truly viable long term as a replacement for DVD).
