Of course they won't; my current GPU struggles with 4k gaming with low effects and keeping fps steadily in the 30's, and that card set me back 1000$ alone, and then you need the rest of the hardware to keep up.
Such a console would cost a small fortune, even rendering 4k games at 30fps with practically no effects or AA etc. would be a humongous task in itself.
I'd be happy if it played 4k blu-ray though, been looking to get a 4k player, I'm buying a 4k TV this spring/summer anyway.
