Im not so sure MGS4 is going to be outsold by Gears 2 anytime this year. Eventually it may be very close, but by the time Gears 2 is released, MGS4 will be selling strong in every region in the world, and the PS3 install base will be within 4-5 million of the 360.
Gears 2 isn't going to sell as many copies as Halo 3, thats certain. By the time Gears 2 is released, MGS4 will have atleast 3,000,000 sold WW, and still be selling strong. Judging from initial impressions its going to be epic in every way including graphics storyline and gameplay. So new comers will eat it up, old fans must have this game because its a finale, and finally Japan has a huge game that it likes along with the US.
So really im going to come out and say it. MGS4 will sell more copies by years end than Gears 2. Its the first game with a global release date on the PS3, and the first game that actually appeals to the entire install base. MGS4 won't have any competition at all until November.
