It looks promising to me. I can already tell that its going to be more aggressive looking than the E92 LCI.
Personally I expect the same growth with the 4er coupe/convertible as we saw with the F30 compared to the E90 (with the same drop in weight).
However, we can't tell a thing until at least the FEP stage starts. So I will be reserving my judgement for that.
Can't wait to see M4 prototypes out & about.
