The first set of photos is the standard 220i/228i in modern trim seems like.
The M235i will look much sportier with more flare like any other M Sport package does on any current BMW line.
I currently drive an e82 135i, I personally can't wait for the M235i. I think BMW has hit a home run on this one. This is the car all the enthusiasts want. Is it a true M car? Maybe not, but it is really close to one and I'm sure the driving experience will be something special.
Everyone who's hating on it is either regretting their 1 series purchase or has no idea how awesome this M235i will be, especially with the LSD option ticked.
There's no reason to buy a 435i M Sport unless you're looking for more room and maybe more of a distinguished look.
Just my .02
