These new systems are mid-range PC's. There is nothing special or magical about them. I do think they'll be hitting 1080p at 60fps for many games like Wii U is now, but it takes some programming time and skill. As far as 4K goes, it's pointless for all but the largest of TVs at the closest of distances. The human eye can't really pick up the difference. It's more important for game developers to focus on detailed, beautiful worlds than higher resolution beyond 1080p.
