And that means what? Does that mean you won't be getting next-gen games on smaller media discs? No, of course not. The compromise wasn't made within the hardware, as traditionally done, but it was made on price. That price has and will continue to affect PS3's chances of long term success. Next-gen gameplay isn't about strict disc size limitations, because that's thinking purely from a content perspective. The limitations in the capability of the console being reduced (more horsepower, better usability for users and developers) is far more important than how much a single disc can store.
Why wouldn't it? What can you really say is absolutely better for games: size of a single disc and the possibility that the user has to swap discs, or making your platform more accessible to more users and therefore more palatable to publishers & developers to risk making games for those users? More users is always a better choice, because, after all, this is still a business.
Next-gen gaming doesn't just mean better-looking. Better playing and looking games don't need Blu Ray-sized discs. The definition of next-gen and what is important to the end-user is already changing. One needs only to look at Wii's or X360's success to understand that. The vast majority of people don't really give a shit about the size of the disc. Oh, they'll spout off the bullet point of how PS3 can have 50GB discs, sure. But they won't care about that once you give them a game and they're having fun with it. Once they're enjoying it, specs mean nothing. What's really preventing those platforms from thriving for the next five to six years? Nothing.
Too many people are suckin' down that bullshit about Blu Ray being necessary for the games of two or more years down the line without even thinking about what they're agreeing with. Someone can come in and say, how are you going to get those next-gen graphics onto a DVD in a year or so? Right...let's wait a year or so and see how PS3 is at the bottom of the hill while the masses are 'suffering' with shitty ol' DVDs on their PC, Wii, and X360, shall we?
