Don't know .. . don't care. Both machines look impressive, and I expect great stuff from them both. I couldn't care less about the gap - however big or small. As long as multiplatform games are not gimped on my platform of choice I'm happy, and for the other platform as well. It would be good if people didn't have to experience gimped versions of a game, irrespective of their preferred platform.

Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
