I predict the sales to be like this:
Super Mario Galaxy: 11 million
Halo 3: 5.5 million
And here's why... The 360 hasn't been selling so great as of late, we all know this, we watch the results every day ;). I expect that 360 sales will follow the original Xbox's sales meaning around a 25 million install base. There are too many problems surrounding the system and the people at Microsoft in charge of the box and this is leading to mainstream negative press towards the box. Not as many people are into FPS's on the Xbox as many people seem to think on here. Sure they sell well, but they've been selling to the same crowd since release. You'll find that the same people who bought Gears are the one's who most likely will get Halo 3, gears has sold well but not EVERYONE who owns a 360 got that game.
Keep an eye out for the Insider Trading allegations, we're going to see this hit the mainstream press real soon. This won't go over so well with the working man.
Also, a few of those Halo 2 sales were Halo 2 played on the 360, Halo 3 probably won't get that boost as Microsoft's future in the console market is not a sure bet.
Prepare for termination! It is the only logical thing to do, for I am only loyal to Megatron.
