I'm sure the natal control scheme will be an option, but I think microsoft like to sell their wireless wheel as well, so I'm sure it will have both control options.
Besides, I don't think the hardcore racer crowd will really latch onto the natal interface. I think a racing game using natal only needs to have karts with turtle shells, or at least the microsoft equivalent to that.
Edit: oh, and BTW welcome to the chartz :)
