I am a bit suspicious as to the "official" supposition. The quality of the photos do look quite good (as already mentioned). However, the wheels in a perpetual state of spinning look a bit suspicious. Also the departure from existing BMW design features and trends also seems a bit too radical (license plate location, pseudo side vents, trunk lid shape, etc.). Although I like what I see I would not at all be surprised if the real design is yet to be shown.
For those of you wanting/hoping/dreaming for E90 pictures/articles - don't hold your breath, all the lime light will be on the E92 for some time.
PLEASE, SOMEONE - HI-RES SCANS APAP! Thanks!
