Those who have enjoyed the Call of Duty franchise's previous outings on Nintendo platforms will surely be disappointed to learn of retail outlet GameStop's omission of the upcoming Call of Duty: Black Ops' Wii incarnation on its pre-order listing.

Activision has yet to officially announce which systems will carry the title, so it's all speculation at this point. But based on this new development, however, it's looking more likely that Black Ops will either unfortunately see a delayed Wii release or possibly none at all.

Treyarch, the developers of this year's entry, have been Wii-friendly for past Call of Duty games, delivering versions of their previous entries Call of Duty 3 and World at War. The studio also ported Infinity Ward's Call of Duty: Modern Warfare to Wii in November 2009, two years after the game was originally released on PC and HD consoles. The Wii lacks a version of Modern Warfare 2.
