Was that official? I mean, I'm sure thats the case, i just don't remember reading an official statement. Last i heard, they wanted to focus on the PC version so they put the WiiU version on hold so they could combine their efforts. I haven't tried the PC version, so i don't know if they are still focused on it and continuing to update it, or if they just gave up on it.
If they are still supporting the PC version, i think once its to the point where they are satisfied, they may go back and complete the WiiU version. Even if its still a year off, it could be a decent free-to-play/pay-to-win game. As long as it doesn't take the spot of a proper Ghost Recon release which I'm sure is coming at some point.
