Here's my share. A real major upgrade from my previous 450D, but doubt 5DII users will notice much difference in terms of sharpness and stuffs.

It's very hard to tell at this magnification. The lens fungus I've seen tends to have thin tendrils - fingers, if you like. Very thin - like 1/10th of a mm of thereabouts, is white or grey, and spreads from a centre, often near the edge of the lens. To be honest, therefore, this does not look like the fungus I've seen - more like some sort of bloom or humidity on the inner lens element - possibly oil migrating from somewhere.
If you are sure this is fungus, it needs urgent attention. A good clean can remove fungus, and prevent it coming back for quite some time, but if you leave it, it will etch the glass, and then the lens is toast. I've cleaned lenses myself by dismantling them, and cleaning all the parts in regular vinegar, but I would have to pretty desperate to do this to a modern EF lens - I've only done it with low value antiques.
If this lens has any real value, I would get it to a service centre, if you really think it's fungus, rather than attempt something yourself.
But unless you live in a very humid, hot or tropical climate, I would rather doubt this can be fungus in such a new lens.
Key to preventing lens fungus is to keep the stuff dry. Even in England, I keep my top lenses in a Peli case with dessicant in, which keeps the air inside nice and dry.
Here is a article to help you.
Is anybody else as crazy as I am, and keep coming back to this site every hour to see if there is any new mentions?
Yes, I'm as crazy as you are.
20+ pages in less than 24 hours... I smell the awesomeness of Canoners.
Anw, chill the crap out guys! Relax! $3500 is a RUMORED price, RUMORED. Even if it's this price, I'm pretty sure Canon has specs and such to justify it.
Less than a week to go to a long-awaited Canon breakthrough, so hold your horses and we'll see the announcement together with the price tag.
It's not about the money, money, money...
I was with you right up to that point.
