I still don't think COD Vita is going to be as big as people think it will be.
COD is a game husbands and boyfriends play when wife goes to bed. If they could play the game, online whilst their missus is watching Eastendale Street - it will be bigger than hula-hoops.
Okay, forgot everyone who plays COD lives with a partner that doesn't allow them control over the TV.
While your sarcasm is noted, Songwriter does have a point: I'd wager a fairly large proportion of people who buy CoD (and FIFA, come to think of it) would be husbands and boyfriends. You don't get silly millions of dollars selling a game only to teenagers and students. It'll probably still be outsold by the 360 and PS3 versions, but if Activision/Treyarch plays their cards right it could be quite the system seller for Sony.
(Practically zero chance of it not being a copy and paste of the 3DS version, however).
