Sheesh people, these are pre-alpha build demos. They aren't going to be very precise, there's a lot of codding left to do. Also, not even the nunchuck is finalized, so there is room for improvement.

Man... this thing needs to be precise in shooting/pointing at screen.

That's the only thing I expect from it! The wii does not do this well, but this thing does it even worse?

How the Wii does not do pointing well? I never have a problem when selecting channels on the menu or stuff like that. And for the method it's implemented (using the sensor bar to know where are you pointing), I'm almost sure it will be better for FPS than Sony's control. Just imagine an FPS game with Wii Sports Resort Archery controls, and that will be similar to what the PS Move will do for FPS.
