Me too mate, the last sightings were some time ago on September the 3rd, and nothing since
Going by the time of the M4 concept which was 11 months or so before the M4 dealer launch, then I believe there is a chance we may see something early next year in concept form, also from the way Scott said there won't be a "production" M2 unveiled in Detroit, with emphasis on the production word...
I can't wait, I already have my M2 number plate waiting to go on
