Well at least you put thought into it rather than just saying highest selling halo!!! And I have no idea. Halo is a hard series to call. If it was GT I would say less than the first one of the new generation but Halo seems to just be going up each time a main one is released. But where will it stop I dunno? I'm gonna say 10mil as a pessimistic estimate.
