it's really not nearly as different from the E70 as people want to complain it is, visually. Different nose and rear-end, but nearly identical shape and proportions otherwise. An evolution to the newer styling and as much as I still love the E70, the F15 does make it look old. Some people will just always prefer the old styling to the new, until the next generation comes out and the F15 is the "best ever"
The overreactions are both comical and annoying. It's really not night and day. Pics sometimes deceive, watch all the videos and you'll see how similar they actually are... And better still, now we can start seeing them in person.
