I know that mrstickballs reply makes sense...but I like conspiracies.
Its actually because no one wants to piss off microsoft. If you don't make a game for their console they make it personal...and will put you out of business. Hell...ther eare roumors that they made the first xbox only because bill gates couldn't get a ps2 in stores when it came out in 2000...and he got angry and decided to put sony out of business.
This is why to 360, nintendo doesnt matter...
