I'm wondering whether it'll end up being awkward, though, just from the way it's set up. Basically, you're free to move the controller around in 3d space. X, Y, Z, and 3 degrees of rotation ('nod', 'shake', 'tilt'). But at the same time, you're also using the same piece of equipment to handle 2 analogue sticks and a lot of buttons - all at once. It sounds daunting.
