Individual games rarely do anything but provide a small bump. It is overall lineup that boosts the base amount of sales per week/month.
The 360's last 4 months of 2007 setup for a even better 2008. The 360 library is so strong (and will continue to just get stronger in 2008) and that is what matters. To new console purchasers Halo 3, BioShock, Mass Effect, best versions of most 3rd party titles, etc. etc. is the reason why the 360 will continue to lead.
The 360's history of software sales and current install base has insured that 3rd party developers will have to be heavily lobbied and paid large amounts of cash by Sony to make a PS3 only game.
Libraries sell systems not individual games
