They'll definitely be on par, graphically, even though that won't be the main attraction. People always seem to 'forget' that, of their consoles that had real competitors, before the Wii, two of the three were the strongest of their generations.
But I believe they'll have some sort of tracking mechanism that can be used in lieu of an actual controller. Possibly some type of projection that can 'beam' a hologram of a controller or in-game objects for you to interact with. PS3 is already seeing the beginnings of that first part, and I definitely think the second will be possible in 5 years' time, for a reasonable price.
