That was never a goal of the system. The "4K" is referring to video playback and support for 4K content, not games. This should, however, get them to 1080P @ 60FPS for pretty much every game in the library, and they've said that there will be an update path for developers to allow their games to support the new hardware performance. I think it's one of the biggest wins in consoles, that we've reached the point where it's possible to have nearly perfect backwards compatibility with older games while hardware continues to improve, with only a patch update to the games to support ever-expanding hardware performance. It's straight out of the PC playbook, to be certain, but at console price-points, with console-level reliability and ease of use.
