I originally bought MW3 for the 360 because I prefer that system. Some friends from work got it for the PS3 recently. I found a REALLY cheap PS3 copy for $22. I already have the Elite premium for Xbox.
Will that membership carry over to the PS3, or would I have to purchase it again (which I will not do)? I want the new maps for the PS3 but I wont purchase Elite membership twice.
