All we know about the upcoming Vita iteration of Call of Duty is that...it's coming out for the Vita. All that is about to change next week, as more information will come out at gamescom. So in other words, the game still exists.
Michael Sportouch, Activision's Euro VP stated that "you can expect us to deliver a true Call of Duty experience," when asked about the PlayStation Vita version of Black Ops, entitled Black Ops: Declassified.
The game will reportedly be optimized for gamers on-the-go, and deliver the most intense handheld CoD experience to date, with Spec Ops and multiplayer gameplay. Well, all that sounds good I guess -- hopefully the game will deliver later this year.
