I already pre-ordered mine!!!!
Like some have said, if a worthwhile controller existed, moto-games would evolve to take advantage of the more sophisticated controllers and the controllers would evolve to cater to more sophisticated riders in the evolving game market.
Remember how much it costs for a stationary "race car" rig:
Logitech G27 = $250 on Amazon
PlaySeat = $300 on Amazon
Total = $550
Have you priced full motion sim rigs?
The CXC Motion-Pro II starts art $45K here: http://www.cxcsimulations.com/motion-pro/configurator/
SimXperience Stage 5 Motion Racing Simulator starts at $17,500 here: http://simxperience.com/Products/CompleteSimulators/Stage5RacingSimulator.aspx
Blue Tiger Motion Simulator is so expensive they offer leasing and do not publicly list purchase prices here: http://www.bluetiger.com/buy.html
If any of you send Allan $17,500 I'm sure he would be very happy to build you an entry level bicycle frame motion moto-bike-controller ~ or ~ send him $45K and he will provide a full motorcycle frame, bodywork & suspension simulator system.
Personally - I can't freaking wait to get my moto-controller!
