Ubi Soft preparing to rush the system at launch. That seems to be working out for them as some of their Kinect launch titles are getting sequels.
As for the game being an MMO, I wonder if that means the Wii U online structure is an open free-for-all. Ubi Soft probably plans to have a more substantial U-Play service if that is the case.
While it would be nice for Nintendo to have some sort of universal Wii U online identity and account service, I'm going to assume that is not going to happen. It can't be too hard for Nintendo make one, can it? I mean, Club Nintendo stuff must already have some of the work done.
