I don't identify with any company. I'm a fan of many games and their creators, but it's not like I have ever felt let down by any of them. I was a fan of Sega and Nintendo back when it was just them. I'm still a Sega and Nintendo fan, but now I'm a fan of other game makers too. I have all the system with games that I want to play. Nintendo doesn't need to win me back because I never left them behind for greener pastures. So long as Nintendo makes Mario, Zelda, and Metroid games I'll be there. But so long as MS makes Halo games I'll be there too. If Sega still made hardware I'd buy that too, but since they don't I just enjoy games like Sonic Generations and Binary Domain on other platforms.
I do mainly buy 1st party Nintendo games for Nintendo consoles and rarely buy 3rd party exclusives. For multiplatform games I almost never buy them for Nintendo machines.
I guess Nintendo could do something to people to buy 3rd party multiplatform games on their consoles. But that seems like an uphill battle since both Sony has Trophies and MS has achievements. It's going to be hard to convince people to buy the same games for Wii U that they can bolster their gamerscore on the system they have now. Even with a graphical facelift.
