Now that the Nikon 80-400mm upgrade lens in now in the hands of customers and reviewers, perhaps Canon will think it is now safe to announce their new 100-400 lens (I'm hoping for 200-500 F4 non-push pull - probably would be too heavy) version.
If Canon were to release the 100-400 II, what would be the chances of Canon retaining the I in its lineup? I believe the II will be priced at least
$ 1,000 - $ 1,500 higher than the I version.

When it comes to gear, it is better to vote with your wallet. Bitching on online forums like a lunatic doesn't get you anywhere!
