Maybe it's got something to do with cost. The new launch is almost half the price of the current 16-35mm lens.
I am sure you are right. But that being the case, the easiest way to keep the cost down is to keep the existing lens. OK it was only an AF, not AFS ...but compared to the 17-35 f2.8 there is not IQ difference at f5.6 and smaller!
When I bought my 17-35 to replace my 18-35 I had to try 4 examples before I got a 17-35 that was noticeably sharper than the 18-35. I nearly gave up and stuck with the 18-35!!
