This is not a Blu-Ray disc, it clearly states it's a new type of optical disc. So the PS3 wouldn't be able to play it most likely. Or if it can, then the 360 (and maybe even Wii) probably could, too.
I'm not gonna reiterate what everyone already said about how hard it would be to meaningfully take up all that space for a game, but it could have other benefits. For instance, every single episode of the Simpsons could probably fit on there, and they've been going for twenty years. Now THAT would be cool.
