Another cop out. Just because they shifted away from graphics being important doesn't mean all of their philosophies changed. Maybe my evidence isn't completely rock solid, but it's still better than your speculation that Nintendo just wanted to go in a different direction. You have no evidence to support that or at least you haven't provided any.
Analog sticks have had a FAR bigger impact on gaming than Motion Controls. I'd consider their introduction more innovative even if it wasn't a completely new idea. "While a novel device is often described as an innovation, in economics, management science, and other fields of practice and analysis, innovation is generally considered to be the result of a process that brings together various novel ideas in a way that they have an impact on society."
Motion controls were exciting at the time. We had seen dual screen set ups before. By Nintendo no less. So of course there wasn't as much excitement. Also Nintendo did a good job of marketing the Wii as a casual console which is honestly what it was. Nintendo doesn't drop good ideas. Unless you can prove that they have before, then precedent shows otherwise. Also the Gamecube was graphically superior and it didn't matter it still got slaughtered by the PS2, so obviously just having a graphically superior console wasn't a good idea.
2 subpar systems. The Wii may have been a financial success but you're being obtuse if you believe it even came close to approaching the library of the PS3 or Xbox 360. There was a reason fans were upset with the Wii. It appealed to the casual market and sold really well because of that, but I don't see how anyone who considers themselves a gamer could've solely played on a Wii. You could easily do that on the PS3 or Xbox 360.
Microsoft may be losing money but you don't see people complaining about a lack of games on the Xbox 360 or the Xbox One.
