Im kind of in the same boat as you, where I own an Xbox and also an Elite founder, but im thinking of picking up on another ps3 (my third) haha. but anyways. alot of people i know play on there so i wanted to get MW3 on it as well. As Im sure you do have to pay for elite again on the second system, and if this is the case I might consider doing so. But the biggest question i have is if im a founder, and I have both PS3 and Xbox linked up to my founder account will I be a founder on both? or just on the xbox?
