LOL at anyone who seriously thinks the game will sell less than ODST.
What he said is probably right in fairness, of all the games launched on each plaform this year then LT sales at the end of 2010 will probably have Reach on top due to how front loaded it will be. Cod will sell more as a multiplatform title but not on 360 sales alone.
GT5 will not sell close to Reach first week, look at past sales trends of driving games, they're just not front loaded.
