I have some great news for people playing Call of Duty: Black Ops on the Wii. (You're out there, right?) Treyarch has confirmed that a patch for the title is now available, fixing a number of issues you were complaining about.
As for downloadable content for the game, Treyarch doesn't sound so sure.
"Many people are also asking about DLC on the Wii," Treyarch writes on its forums. "There is still no information on any potential DLC for the Wii, but we will be sure to update this space once there is. Thank you for your patience."
Translation: don't hold your breath. The full list of fixes the patch brings can be found on the official Black Ops forums.
