The design does not look radically different though. It's an interesting fact that the 16-35/2.8 is the first L lens to go into the third iteration - kind of an admission by Canon that they didn't quite get the first redesign right somehow.
BTW, I'm a happy camper with the f/4 IS. I know many people feel the same. A 16-35/2.8 was the default choice, but... Not anymore. Instead, it has become a niche lens (and the situation isn't helped by the very high price of this new unit).
