Whereas the F30 is not that huge of a leap from the e90, this is going to be a COMPLETELY DIFFERENT car in terms of shape and size.
I, for one, am excited at the notion of a fresh new design (I've heard 'Baby 6 series') for the coupe, and I think you all are a bit premature on your judgement.
That's why we're here though, to make comments and pass judgement, so have at it!!
