Good.
Single-stick (like classic Star Fox) does what it does, and well. Twin sticks are poison. Motion aiming is a full replacement for twin sticks, but you can't design encounters for it the same way you do for a single stick (recall the changes in Metroid Prime, where 1+2 were built around a lock-on and 3 was built without).
Agree 100%, gyro controls work decently well but IR blows them away in all respects. Plus using the Wiimote & Nunchuk is far more comfortable than the bulky gamepad.
Admittedly, I think I would have liked it if Nintendo had committed to a second full generation developing around the Wii Remote Plus as a standard, especially because we barely saw it exploited to its potential. It would have constrained them with respect to certain genres where the second stick is indispensable for free camera control (Zelda and Xenoblade both come to mind), but rail shooters aren't one of them.
If Nintendo dumps the second screen for the next generation, I could see games like Splatoon persisting through something like a lightweight Pro Controller with a built-in gyro. That would be conservative for Nintendo, but perfect for players whose main concern with the Wii U GamePad is the bulk and the difficulty of tracking both screens. But I think they have enough people hooked on motion aiming by now, myself included, that going back to twin sticks alone without gyro (like a certain crowd keeps demanding) is outside of the realm of possibility. And thank heavens it is.
