No, not that I 'like' all the changes in the E90 from the E46, but I don't like 'retro' looks, such as the new Mustang that's coming out. To me a 'retro' look is like saying "Here's what we wish we'd done back when we first made it..". The E36 is classic, I'd hate to see that spoiled by a new car trying to look like it. The E36 was a big step from the E30. The E46 was mostly cosmetic, no 'huge' changes occurred. The E90 will be the next big 'change' in the 3 series.
The E90 isn't all that bad looking, and I'm sure it will be a BMW through and through, regardless if it's outside doesn't perk all of the 3 series followers to instantly go spend a fortune on one. It's not out yet, so who knows what final touches and changes will be done to it(Really who knows what all these photos are that are floating around.. So much photoshopping going on, I think I'll wait till BMW says "Here, look at me!"). I think it'll be 'correct' when it hits the market, the 3 series is BMW's bread and butter. They can't afford to lose the sales growth they've experienced the past few years.
And when it's all said and done, BMW will do whatever brings in the most $. Hopefully us Fanatics can enfluence BMW more than the folks who bought one as a social 'badge'.
