If you take a look at the interior picture, you see it has the new air con panel (as in X1). Heated seat buttons are now located there. This same change will be in all E90/E91 from September production.
Info I got was that E92/E93 would also get some grooves to hood, as E90/E91 got in LCI... interesting to see that they are not visible in those pictures.
Otherwise as it can clearly be seen, there is no big changes coming. Passive eyebrow as E90/E91 LCI has, some new bumpers and thats about it. Couple of new colours are coming as well + some new upholstery combinations. I also heard that the 335i will get a minor power increase.
