Zavvi, an online retailer, is carrying listings for Black Ops 2 on both the Wii and 3DS. The listings offer November 13 release dates. Activision has yet to officially announce anything, so it could just as easily be a misslisting, on Zavvi’s part.
Activision has, however, long since confirmed the release date for the 360, PS3, and PC version on November 13th. The Wii U eddition will be released the same day that the console is, on November 18th.
Just last week Activision announced a Call of Duty Black Ops: Declassified release date of November 13 on Vita.
