Someone correct me if I'm wrong, but I think the extra stop of IS will make the 70-200 f/2.8 IS II canon's most hand holdable lens for still objects. (When used at the 70mm end, the extra stop of IS moves it ahead of the 200 f/2 and the 24-105 f/4). Kind of neat, if true.


Personally, I'll have to see the price and read reviews (Bryan's review, anyway) before I can decide if I should upgrade. It will take a significant IQ increase to move me.
