I think outside of Nintendo only EA has a real chance. With FIFA and the other big games they have they'll probably take most of the 'hardcore' market with them. I don't see any of the others having a real chance. Activision would need to have Call of Duty be so successful that it can carry the rest of the company, assuming World of Warcraft or it's potential successors don't become console-exclusives. Ubisoft will be lost and I don't see Sony or Microsoft bringing enough to keep heads afloat either. Hypothetically Microsoft could, because they could pump unlimited funds into XBox 'just because'.
