I posted this before: if the reviews indicate that the newest pair of 70-200 Canons are as superior to their predecessors as the 100-400 Canon II is to its I version...count me in.
Unlikely to be the case. There just isn't as much room for improvement on the 70-200 II as there was on the 100-400 I. And, keep this in mind:

... it does not matter if not a single person upgrades from the previous version, these lenses sell a lot...
Yes..... at some point in the manufacturing cycle it starts to get hard to get parts and a "new" version has to come out. Sometimes the differences are invisible to us, such as when the internal electronics gets upgraded, or they use a different lens coating.... but at some time, you end up with a whole lot of pending changes, one of which is going to mean a noticeable change, and you roll everything through to the latest tech....
On this lens, you can expect that the machining will be to higher tolerances....that makes less copy variation and that simplifies manufacture, but does not have much impact on image quality for the average lens.
The coatings will be better..... there will be less flare, but none of us will be able to tell the difference.....
Florite glass is more common now.... there MIGHT be more florite elements, and that will reduce chromatic abberation by an amount too small for us to notice.....
The IS system will be better. It will be faster and it will be more accurate, and it will be quieter than the F4 IS is now.... We will be hard pressed to notice the difference....
The design software has improved and the polishing of elements will be to greater precision. This will give us a sharper lens, and if you look real hard, you wil notice the difference.
Overall, everything adds up, but the differences will be hard to tell by eye. The existing lenses are VERY! good and there is only so much space for improvement. The market for these new lenses will be new buyers.... sure, a few of us will upgrade, but the numbers will be so low that it is neglidgeable
