Pointer controls are pretty much the only thing on Wii that was an absolute improvement over what was previously available on consoles.
Keeping motion controls but removing precise pointing would be exactly the wrong way to go.
It was slightly less accurate, but Skyward Sword's use of motion controls for pointing wasn't bad. I actually liked being able to use the pointer without having to point at the screen. It was like using a mouse.
The gamepad uses motion control for pointing as well, and it's pretty quick and precise.
