In this rare instance, I absolutely LOVED them. After a brief adjustment period (switching from 2 to 3), I ended up loving the motion controls the most. In fact, between Corruption, The Conduit and a Wii version of some Medal of Honor game, the Wii motion controls became my most preferred First-Person-Shooter setup.
If I could have the option to use tilt controls like in Splatoon I'd be OK with that. I don't think they will make motion or tilt controls mandatory, as 97% of the games dont (unless it's the original wii). We will be able to play however we want.
