You can bet that one of the games for the Wii U and 3DS is a new Mario and Sonic Winter Olympics game.
Well, they've already done the whole Summer and Winter games thing. I wonder if a 'Mario & Sonic at the Paralympic Games' would be something they would consider. Mario & Sonic wouldn't compete of course, but would play the roles of officials or referees (think Punch Out!!). That's probably unlikely to ever happen, but I actually think that would be a pretty neat way to introduce children to the idea of people being differently abled (which for some very young children can be confusing or even frightening).
