4K? They can't even comfortably hit 1080p with these new consoles. Even the PS4 has problems doing it in single player content when the machine has to worry about things like AI. I suspect 4K video content will be another story though (not that there is much of that right now either).
Even modern PCs struggle to game at 4K. It will probably be a year before we get decent 4K monitors and graphics cards beefy enough to push them that don't require enough electricity to power a third world nation.
