You forgot WoW: Cataclysm, which will probably sell 4 millions copies in the first 24 hours alone, and over 10 millions lifetime.
And Piracy is irrelevant to Starcraft 2 (and any PC game) when it comes to sales. No one in their right mind would play Starcraft 2 without MP, unless you're one poor motherhubber.
