A listing on Ubisoft's games directory has confirmed a released for Tom Clancy's HAWX on the Wii.
A version had been strongly rumoured last June, and popped up in listings on retailers/other gaming sites in late 2008. It seems now that the project is finally official, with a page on Ubisoft's own website, stating a March 2009 release.
No PR has been released at time of writing, so there still may be a chance it's a misprint, but given strong signs from the company and industry rumblings, it's most likely definitely on the way.
