There is zero reason for them to cancel this. It's already pretty much done, the game comes out within the next few months, and Ubisoft has already spent all of the time and money and manpower making the Wii U version. It would cost them money at this point to NOT put it out.
Splinter Cell sold shitty on Wii U, but then agian, it didn't sell very well on any platform. Assassin's Creed has already sold decently, and will have at least sold as well as ACIII, and Rayman has done almost 300k.
It just makes no sense to not release it.
