PS4, because it'll be reasonably priced (no way Sony will repeat the mistake of making it $500/600) and according to recent articles, Sony is confident they'll be first to market.
Unless the 720 massively undercuts the PS4 in price, then I'll go with PS4 winning next gen. Plus the future of Halo and Gears of War are both in question. I can't see Halo 4 being as big without Bungie, and Gears is 3rd party so who knows. Sony on the other hand always has strong first party.
