I think Sony will do pretty well as long as they don't repeat the PS3 launch (which i'm confident they won't). Sony has done a wonderful job of turning around the PS3 this gen and I definitely believe they will keep the momentum going.
Though Microsoft simply has more money to blast advertisements and can afford to take more of a loss by selling the system cheap. Microsoft also has a pretty sturdy grip on the US.
It'll be interesting. Seeing as how closely the sales between the PS3 and 360 are this gen despite the terrible PS3 launch and first couple of years. I think as long as Sony doesn't make those same mistakes it'll be off to a much better start.
