Way back in 2011, Ubisoft announced Tom Clancy's Ghost Recon Online and stated it would be coming to PC and Wii U, however, the developer has since put the Nintendo adaptation on hold while it focuses on the PC version.
It seems the situation hasn't changed as the game's official Twitter account confirmed earlier that the Wii U version remains out of active duty:

Ghost Recon Online is already available on PC but it appears Ubisoft is still labouring on it and will not be considering the Wii U iteration until it's fully finished.
Ubisoft has been an ardent supporter of Wii U with games such as ZombiU and Assassin's Creed III - and Rayman Legends and Watch_Dogs still to come - so we're still holding out hope the development team will get back to work on the Wii U edition in time.
