These are my guess.
185/3.5 macro replacement
100-400 IS replacement
My hope is that Canon will speed up the 135 and add IS to it.
I would like to hear from an replacement of these bodies or lenses too.
If Canon will announce one of these things tomorrow, maybe we can buy it in the end oft 2014
(My preordered 70D will be shipped at the end of October! - After 3-4 month of announcement )
