I'm not so sure it works that way. It may just be that if they pull support for PS3, it will be business as usual just minus PS3 porting. But I'm not involved in the gaming industry so I'll just say, I don't think so.
Though on the flip side Activision may have additional resources to spread across the other platforms if they aren't working on PS3 porting. But, I don't know Activision and many TP right now are just making everything multiplat.
Bet between Slimbeast and Arius Dion about Wii sales 2009:
If the Wii sells less than 20 million in 2009 (as defined by VGC sales between week ending 3d Jan 2009 to week ending 4th Jan 2010) Slimebeast wins and get to control Arius Dion's sig for 1 month.
If the Wii sells more than 20 million in 2009 (as defined above) Arius Dion wins and gets to control Slimebeast's sig for 1 month.
