I think the PS3's levels of software sales are doing well enough in NA alone to justify continued support.
The thing is, isnt it easier to develop ground up for the PS3, with higher initial costs, then port to the 360 and as such have two identical versions? Im sure this is how COD4 was done because the versions are practically the same, unless they somehow managed to port it from the 360 with no hitches but it would have been a first.
Also, Like many have pointed out its the exclusives that are struggling. R&C and Uncharted have broken the mould a little bit and are actually selling okay, though originally it looked as if R&C would do terribly its maintained its sales since release really.
I imagine uncharted hitting 1 mil early next year and R&C following soon after.
