I think a Wii U sequel would be great. I bet there would be wiimote and tablet control options.
In any case, I think the future for this franchise is VERY BRIGHT!!
Also, I wouldn't get carried away on this report. Some people are talking as if this was a Wii game that got crammed on to 3DS at the last second. But, it had no better likelihood of being on the PC, right? So, let's take this story with some perspective.
