Yeah I still want a tangible controller, I just want head movement tracked.

Microsoft needs to get together with Saitek and develop a full line of flight controls for the Xbox 360. Just like there's all kinds of guitars and drums and mics for the 360 music games.

Flight Stick with the seperate throttle control like the Ace Edge, except much better like the Saitek X52.

Rudder Pedals

Knob and switch module like the ones that Saitek makes for PC.

As many flying games as there are coming out, they can make great use of a full blown system, even offer a high end gaming chair that all the MS/Saitek flight controls can be easily mounted to. It could even be connect by usb to move or vibrate according to whats going on in the game.
