how much the BMW Runflat system (Flat Tire Monitor) did like the wheel change. On the I-Drive screen the message shows up: "Flat Tire Monitor has to be calibrated" [source: www.autospies.com
So theres possibly a production M3 in Geneva, but we've not seen it yet.

The car totally covered in the video is the "production" version, I suspect. Why else would they risk moving it so carefully covered up? To keep prying eyes away is the obvious answer! OK why did the production-CSL concept have a warning about the RF calibration - simply because the system was not installed on this car or the rims do not support the system. Again, just speculation/debate, but Soctts reply seems to support this theory as well.
