We've already seen views from VIN land showing the shape of new side mirrors for the M2 Competition (see
here) and hinting to optional different back seats (see
here).
Detail: it appears that recently the shape of the glass inside the side mirrors has been added.
For the rest: no info surfaced yet about the M2 Competition reveal. Forum fellow MR. quoted January/February 2018 for release + presentation in March 2018 during the
Geneva International Motor Show (see
here). The 1M was revealed late Autumn 2010 (
BMW 1M press release: Dec 10, 2010). Autumn 2017 ain't over yet. Let's wait and see.
