Why do Canon bother to release new versions when there is little improvement?!

One reason that has been suggested around here is that they may have altered the way they build them - moving to more automated/robotic manufacturing, which may save them money one way or another (in the long run). Not every update will show strongly on the customers' end.

Have heard that too - and there may be more changes made under the covers as well - not necessarily improving IQ (which as others note may be getting close to what is achievable at (relatively) modest priced zooms), but which also give greater reliability / more efficient servicing, etc. If nothing else, a new model designation gives a longer support life.
If they didn't bring out a new model but continued with the old one, then the old one would be the current model and have the long support life.

Yes, sorry, my bad: poor use of words by me - what I meant to say was that a new model with (potentially) newer parts, could mean parts stock for future support would likely last longer into the future (based on purchasing the 'current' model now).

If such a new manufacturing process can reduce variation among units within a particular model (“copy” variation if you will), it can be argued that this would benefit the consumer as well, but I don’t know if this has been proven or quantified.

The optical performance of the existing lens was so close to perfect, that even a little is a accomplishment.  Looking at just center sharpness is like reading the specs on a Soiny camera.  You need to look at everything.  The lens had a substantial upgrade across the board, but I would not upgrade from thye old one unless it were my most used lens and my old one was wearing out.

I agree wholeheartedly and would add I would only purchase if you currently did not own a 70-200 f/4 lens. Otherwise, I see no reason not to. Looks great.
That's it, I'm switching to Rollei
