Nintendo's so far ahead of the curve it's surreal. Motion controls being taken up whole heartedly by their previously scornful competitors, and being the first to release a 3D console with amazing array of supporting software.
Sure, their Wiimotes are imperfect and all, but they got the market share, they got the following - they have the consumer base and cash to develop the next generation of tech as they see fit. I would love for Nintendo to bring out a new console in, oh, a few years, seamlessly merging their casual and hardcore crowds and building on the motion-control lessons learned from their own past and Microsoft's ideas.
After all, Nintendo has the most experience with motion controls, and motion controls + large 3D TVs in most people's living rooms would be a pretty damn awesome time to game in
