I like the concept a lot and think the production version will be more pleasing to the eye.
However, it is strange to me that, especially going from the 3er to the 4er moniker, this is the least drastic change from one generation to the next. The E30 to E46 to E92 transitions were major redesigns while this seems almost like LCI update 2.0 for the E92.
