Treyarch director of communications John Rafacz has said the Black Ops 2 studio is completely unaware about development on the PS Vita version of its upcoming shooter Black ops 2.
Rafacz was asked by Videogamer which Activision studio is working on Call of Duty: Black Ops Declassified.
"I don't know," he replied. "With regards to the Vita, all I can tell you is that it's quite literally declassified.
"When I know, I'll tell you."
He was also coy on whether Black Ops 2 will be released on Nintendo's Wii U, as suggested will be the case by a recent issue of Nintendo Gamer magazine.
"Right now we've announced that the game is coming for 360, PS3 and PC. Announcements regarding any other SKUs just haven't been made."
Although Rafacz didn't outright confirm a Wii U version was in the works, he did say "any technology that can enhance the Call of Duty experience, that's a technology that is worth considering."
"There's that core Call of Duty experience and that is what fans expects, so anything that helps advance that is worth considering," he added.
Sterne Agee analyst Arvind Bhatia believes Black Ops 2 will be out on Wii U this holiday and "should contribute to incremental sales of the title and also the Wii U console.
