I haven't really read through all the comments, just skimmed them. Here's my opinion.
Gears of War 2 will outsell all the games you listed. But games like SOCOM, LBP and Killzone 2 will be better system sellers than Gears of War 2. I don't see a ton of people buying an XBox360 for Gears of War 2 if they didn't get one for Gears of War 1. Since SOCOM, LBP and Killzone 2 will be making their PS3 debuts, they have more potential system selling power. Hell, I think a game like Tales of Vesperia, despite it's limited fanbase, will sell more systems than Gears of War 2.
