I would say that Halo 3, Call of Duty MW2 and GTA IV. Halo 3 is definately going to make it, and Call of Duty/GTA IV have a good chance of making it from name recognition and legs alone.
MW2 has a decent chance, but im actually rating COD MW chances higher due to people getting sick of the series and/or staying with older COD games.
GTA IV/V will have a pretty good chance, that name is still massive and the console sales are shooting past 40M so it won't need such a killer attach rate to do it.
100-1 has a pretty good chance since its free! 
Tease.
