More SMGs is just what Black Ops 2 needs. At least it finally adds a snow map. That Mirage map reminds me alot of that one map on WaW.
Maybe it's a remake of either Castle or Courtyard? Like how Treyarch remade Cliffside from WAW on Black Ops 1.
XBOX most likely will get it late January/early February. PS3 a month afterwards. Wii U, who knows maybe several weeks aftee the PS3 release.
