A Wii U version of the game could still happen in the future, but isn't actively being worked on.

Metro: Last Light, the sequel to the bleak 2010 shooter Metro 2033, is no longer confirmed to release on Wii U, according to THQ Global Brand Manager Mark Madsen.
In an interview with Digital Spy, Madsen noted that while a Wii U port of the game "could" occur in the future, work on such a version is not happening at present.
"Not at the moment, it's not in development," he clarified.
"If it does happen, it won't sim-ship with the other SKUs, but if the opportunity arises we'll take a look at it."
Madsen also noted that the game's inclusion in Nintendo's presentation of third-party games on Wii U at last year's E3 was not an inopportune announcement.
"No I don't think it was a bit too early [to show the game at E3]. As we got along in the development process, we just really wanted to focus on what we knew, focus on PS3, 360 and PC.
"The verdict is out on what we can do to maximize the code for the Wii U, and we'll see [what happens]."
Nintendo was way too late in getting the final Wii U dev kits out
Isnt THQ on the verge of dying out? Maybe they just don't want to take any risk and go for their sure thing.
Would that even matter? Sure, the final Dev Kits only recently came out, but its not like they haven't had earlier Dev Kits to work with over the last 2+ years. As far as I know, the only thing different about the final Dev Kit over the earlier ones is the specs being higher.
Big surprise, blame Nintendo speculation from Broodwars.... ;)
