Sony can advertise the hell out of their big budget games, but let many of their small franchises die out (Example : The Last of Us and Sly Cooper).
Nintendo has shown that they can take one of their smaller or dead series and boost its popularity a shit ton (Fire Emblem Awakening, and Kid Icarus Uprising). But they also have failed in showing general consumers the benefits of the Wii U, and they can only seem to market towards kids.
I'll have to see how Nintendo handles marketing Wonderful 101 though since Hideki Kamiya said that Nintendo were barely advertising it at all and thought the game would fail.
Im not too knowledgeable about Microsoft's marketing though but they do have a lot of sales from Kinect games and Halo, so they must be doing something right.
