So I was working on the Excel spreadsheet for the thread in my signature and I saw an extremely interesting trend...
The Canon UWA Zoom in all its variations since the FD days in the '70s has been updated every 5-6 years like clockwork:
FD -> new FD = 6.2 years
new FD -> EF = 5.5 years
EF -> EF USM = 6.5 years
17-35 -> 16-35 = 5.7 years
16-35 -> 16-35 II = 5.3 years
As of today (August 2012) we are 5.4 years from the release of the 16-35L II
If history is any indication here (and it looks strong) expect a new 16-35L III to be released by the end of the year.
Also, given the pricing history of the lens (230,000 Yen same as the 24-70L II) I expect it to remain the same for the new model.
Of course, given the crappy exchange rate for the USD, expect the US price to be around the same as that of the 24-70L II ($2,300)
Release date: by Dec 2012
Price: 230,000 Yen or $2,300.
You heard it here first!
