We're looking at a production concept, not an auto-show concept car. I imagine a few of the more dramatic trim bits won't make it to production, and those wheels look a little over the top - but fundamentally this is the car. I don't see a problem revealing it at all.
Take a look at the 6 series concept, now that you can turn around and look at the actual 6. The concept was very close to the production car.
