According to Crytek, Crysis 3 was meant to have a Wii U version and was finished around the same time as the other platforms but EA demanded the project to be cancelled.
The reason appears to be related to rumors of EA being pissed off at Nintendo rejecting having Origin be the provider for the new Nintendo Network and EA having a lot of control over it. Also would support rumors of EA pulling support for Wii U projects as punishment against Nintendo.
