Ahh I love BMW's strip tease!!
Ive seen probably every single spyshot there is for the F10 and I can't say I've seen a bad angle yet. I think we've all seen enough pics now where you can pretty much make out the exact shape of the body. Only thing left are the smaller details -- lights especially will be important in how the end product looks. But judging by the latest BMWs like the Z4 and 7-series I don't think we'll be disappointed by the lighting elements and shapes!
One thing I'm curious though is the wheels. In these pics
http://f10.5post.com/forums/showthread.php?t=292201 we saw some great looking wheels also on a 550i which I hoped would be standard on the 550. But the pics posted in this thread has less impressive wheels... wonder why the difference.
