Sega has confirmed that Aliens: Colonial Marines has "gone gold" (meaning it's finished and ready for production) on 360, PS3 and PC, but has stated that the Wii U version isn't quite ready yet.
According to Eurogamer:
We asked Sega what was going on. The publisher told us the Wii U version is due out in the Wii U launch window which, technically, runs up to the end of March 2013.
Sega reiterated it had never announced the Tuesday, 12th February date for Wii U. That worldwide date only ever applied on PC, PS3 and Xbox 360.
Gearbox isn't handling the Wii U edition of the game - that honour has fallen to Demiurge Studios - which could explain the staggered release. Presumably Demiurge have to take Gearbox's code and finalise it for the Wii U, meaning the Nintendo version was always going to be slightly behind the others. The fact that it's not a straight port (whatever that may mean) might also have something to do with the delay.
