User blog comment:Drkdragonz66/Treyarch - Call of Duty Heading to Next-Gen Console?/@comment-1055346-20111006201736

The Xbox 720 is unlikely as Microsoft claimed their going to continue working on and supporting the 360 exclusively into 2015. The Playstation 4 I doubt, no reason other than personal doubt. The PSVita, or the 3DS for that matter, don't seem like possibilities due to the fact that Treyarch doesn't make the mobile titles so that seems like a stretch. The Wii U is the most likely because of the recent announcement, and if a game like Battlefield can be on it, why not Call of Duty. But the question of MW3 or Black Ops sequel is still out there. Since Treyarch is developing the Wii port, there is a high chance they are also developing the Wii U version/port. But it might be the Black Ops sequel as they prepare for next year, as well as the fact that Nintendo didn't list Call of Duty or 3arch/IW as games/developers during E3 this year.

To sum this up, my belief is Wii U and Black Ops Sequel
