I wouldn't attach too much meaning to that line. Even smart wouldn't be dumb enough to offer no Cabrio at all.

Pure, Prime, and Passion are distinct models, which may be available as a Coupe or Cabrio.
MY17 453 ED, nothing definitive - "Arriving this summer . . . ". . . now about the 17s - are they even coming. Nothing noticed up here that I have seen.
Available as Pure, Prime or Passion but NO CABRIO?
