I can say it doesn't look like the photoshop image on the top of the page. Honestly, that image looks more like an artist's rendering of what the E92 M3 might have looked like.
In any case, there are many photos posted on this site that really show a good deal of what the new 135i coupe will look like.

This shot of the gray test mule is spot on in terms of what the US-spec car will look like (save for wheels and the tape).
They also told us 3 items that will come STANDARD on the US-spec 135i coupe:
- Moonroof
- M-Sport kit
- Brembo front brakes (and after taking a closer look, 6-piston calipers to boot!!)
