Canon is rumored to announce new 70-200mm f/4L and 70-200mm f/2.8L lenses in June:
"We can 100% confirm that one of the new lenses will be an EF 70-200mm f/4L IS II. We can also 95% confirm that the second lens will be a EF 70-200mm f/2.8L IS III. All of the tips we’ve seen point to this lens coming, but we haven’t actually seen the f/2.8L IS III in writing."
