Because an 8 core CPU and 7850 can play a lot of console ports at 60fps @ 1080p so one would assume a game developed for the hardware could do it too. You still tend to forget that developers can squeeze a lot more out of the hardware set of consoles than they can with PCs. As time goes on and graphics get that much more demanding I wouldn't doubt these consoles will do like the current ones but you can see in some areas where they compromised to get the results. For instance, the grass looks terrible and grass is usually a #1 issue for most games. Making the Skyrim grass look real pretty even tore up my SLI 580 setup.Says who ?
No matter how powerful your hardware, it will always be a compromise between resolution, frame rate and graphical quality. They will still be making that compromise on games in 50 years time.
It really would not surprise me at all to see a whole load of 30fps, 720p games on next gen consoles.
Depends. If I can lie on my sofa and vaguely wave my hand (not arm; just hand) through menus, that's something I'd be down with. The other stuff like integration with games... nah.
