I'm no MS or Nintendo fan... But i want to put what i said in leo's thread in here anyway 
They have the most IP's.
They have produced far more quality IP's this gen than either Nintendo or Microsoft Game Studio, possibly combined.
They don't rely fully on the same series' they have relied on since they first entered the market.
They have (or will have, soon) a game for every genre i can think of.
They produce games targetted at every group. From games like EyePet, LBP to God of War, Uncharted.
