That may have explained the awful steering on this one airship demo this developer was displaying using the system, but that could have just been a problem with not enough fine-tuning of the control-code in the demo. ;/
Editors from Gamespot.com tried the controller at E3, and said it "feels surprisingly tight and easy to use. Flying the plane by tilting the controller is very intuitive."
They concluded with "the controller feels pretty nice and already seems to work well."
