any numbers to prove that it worked or maybe X360 COD userbase had already been bigger in the US to sell more ? I didn't jump on time exclusive bandwagon, never will no matter who makes a deal with whom. I see it as a 2 minute fame for E3 audience that's all.
Besides EA doesn't have a single game to out match COD in sales right now.
As a pure mind-share thing, MS pretty much wrapped up CoD, even if the user-base of the PS3 increased massively over the last few years. They must have had a good reason to keep throwing money at CoD DLC. Personally exclusive DLC does not get me to buy the game. Sure it is nice if it happens to be for the console I currently own but its not a do-or-die thing.
Are we talking in the shooter realm of things? BF might not be as big but it has certainly gained ground. Next-gen I don't think saying 60fps CoD is going to sell it as much as 60fps Battlefield will. My own opinion of course.
