Oh they could very easily, if they fuck up. Sony had too big an ego with the PS3, after the PS2 and we've recently seen the same with Nintendo and the 3DS from DS, thinking that just because they won previously, they can do it again no matter what moves they make. Doing very well the previous generation (in the case NA) can be worth something if you make the right moves. If you don't, it might as well mean nothing.
So bad moves they could make would be not enough unique IP, the real core gamer won't be happy if they think we're in for another gen of just Fable, Halo and Gears, heck even I won't be happy with that .., another bad move will be a high price, anything above $399 is risky. Not upgrading XBL enough Vs. PSN, and launching later than the PS4, or WiiU by more than 1 year.
