Very few games actually play at render at 4K. Even the most powerful gaming PCs would struggle to render that at a respectable frame rate, or hell, even at 30fps.
What Sony and MS are likely pushing is some kind of upscal to 4K which won't look as good as an image that actually renders at 4K. It'll be a while still before we can see that in real time (although there are some 4k films, but I haven't checked to see if those are upscaled or true 4K.
