And Atari will be 1st. Where's my money?
Seriously, Microsoft has been making gains this entire generation. They built up a solid core userbase with games like Halo and Call of Duty, and then expanded it to include a more casual base later on with Kinect. They usurped Sony as the clear home console king (Sony possibly ending up with a 2m or so lead over a competitor is not domination, sorry) and managed to hold the lead against them for over 5 years. Unless Microsoft really screws things up, I think its likely they'll be on top with the next Xbox.
