It shouldn't be too much of a problem for next gen hardware from Sony or Microsoft. Or at least I hope not. I know it will take a great deal of computing power - but that's what next generations in hardware are supposed to be. But will TV manufactures jump to 8k and skip 4k all together?
Sony plans for 4k blu-rays and to make 4k TV early next year. A nicely upscaled 1080p signal on a 4k set would still look rather nice.
4k 3d could look, very, very nice.
When the Xbox came out, with all games running at 720p from launch, there weren't too many of those kind of TV's out there.
