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

I suppose it's possible for the Wii U version to be canceled, but I just don't see it happening. It wouldn't make much sense to put that much work into it, only to drop it at the end of development.

I see it being a Twilight Princess route, where both versions will release, and for some reason the Wii U version will be worth more... maybe? It wouldn't matter anyways though, as the Wii U version will likely be available via digital anyways.
