Wasn't there a private viewing of the ~95% complete production car in Geneva? That was back in March or something - so either SCOTT was pulling our chain about how close that particular model was to completion OR they've potentially hit a bit of a snag and want to make sure the car is right where they want it to be.
It wouldn't surprise me at all if this is just rumors/rumblings. BMW knows how crazy people seem to be getting over the release of official info for the M2.
