i took a look at the sales history and i'll tend to agree with your conclusion, MW2 will probably sell more than halo reach. the halo franchise would have to go up in popularity by around 50% to keep on pace with MW2 with just seems to big of a gap to me. i wouldn't be surprised if reach goes on to out sell halo 3 though.
