If Zelda:BotW delay is going to happen, Wii U version will be cancelled.

I'll say that right now, I'd buy both versions.
The Switch version is the one I'll play.
The Wii U version, I won't even take the plastic off. It'll be in mint condition and if I can even get it signed at a convention one of these days where someone like Reggie, Aonuma, or Miyamoto are in attendance, Oh My God in Heaven I'll make a fortune off of it!!!
