MS... they play it a bit too safe when it comes to games that they publish.
Sony... I don't know. When I think about it, they should be crushing everyone, but they aren't. They're in a tooth and nail fight for second place. I think history is their biggest problem right now. They came in this gen with one attitude and even though they've changed, people might still see them as that way. It didn't help that early on multiplats were generally way buggier on a system that cost way more than the comp and devs were complaining left and right about how odd the programming structure was.
Nintendo... they've had this problem since the N64 and I don't think they consider it to be a problem, but they don't have the support of 3rd parties when it comes to AAA titles. I think it's lasted for so long that people now buy Nintendo systems with the opinion of, "this is a Nintendo player. It plays Nintendo games and nothing else." Every now and then a 3rd party game will do well, but the bulk of stuff thats AAA quality and sells well is made or published by Nintendo and that's the only stuff that the bulk of buyers seem to be looking for. I think a lot of games would do way better (like current sales multiplied by 4 to 20) if Nintendo took the game under their wing and rebranded it with Nintendo characters like Mario Bros 2.
