In terms of buzz, I thought COD4 completely overshadowed Halo 3 in Xmas 07, though naturally didn't outsell it.
Again, MW2 won't beat Halo 3's opening week, but it has a good chance of beating ODST in opening & LTD. Guess it depends on how Microsoft market ODST. If they treat it like GTA DLC, then I think MW2 will come out on top. If they treat it like Halo 3, then it could go the other way.
