hi im new to ps3. never had one. and don't own one yet. i was wandering if I can use the vita for co-op playing (couch mode) so I don't get a split screen on my tv when im playing cod with my g/f. to put it another way, can the vita do the same for the ps3 as the wii u controller does for the wii u? maybe a dumb n00b question , but i can't get a decent answer found on google. Thanks!
