I'll go with 6.25 million but I haven't really checked on Halo 3 / ODST or the release dates (like is it coming the same week worldwide?). My guts says a good portion of the Xbox audience is burnt out on Halo and Call of Duty but they're being replaced by new gamers roughly as quickly as the old ones burn out - not sure the growth in userbase from Halo 3 / ODST / MW2 until now really helps much. Three mainline Halo games on one system is alot (especially in four years) - even Nintendo doesn't try that with mainline Marios (NSMB is different from Galaxy 1 / Galaxy 2). My guess is bigger opening week that Halo 3 but a much faster drop off, probably a similar total through 10 weeks...so hopefully thats about 6.25m but as I say I haven't checked the figures / release timing.
