PS3 WW SW will be on top of the 360 except for 2 weeks until Reach (bets?)

what kind of software could the beta move? it's not like the beta is being sold on a separate disc. and as we've seen with halo odst, everyone who wants to play halo already has a 360. hardware hardly moved on odst's launch. for a beta, it's not going to move significantly either.
