At this point I'd be surprised if the Wii U version even sees the light of day.
But then why they show us the new trailers with " PS4/XBO/WIIU/PC" on the title?
That´s a Namco Bandai trailer yesterday.
Also, why they told everyone less than a week ago that the WiiU and SteamOs versions are coming this year?
Do you really think that this is a blatant lie? Because that would be a HUGE scandal.
I wouldn't put it passed a third party to blatantly lie to Wii U owners, unfortunately. They may want to delay the resulting backlash until after the primary versions are out.
