And there have been rumors all over the internet about the 100-400 getting an update, which hasn't happened. There are many other lens update rumors and I'm willing to bet that some of them won't be updated for years to come.
The folks at CanonRumors are not always right, but they were pretty on the ball about the 70-200/2.8L IS II -- already reached CR2 status on Novemver 12:

On November 17, they correctly predicted the January release date:

Of course, they've done this before with rumours which did not come true, but I was sold when I saw the lens element map on December 6:

I was watching the 70-200/2.8L IS rumours very closely because I was going to buy one for an upcoming wedding next week, but seeing all the evidence that a Mk II is on its way, I decided to rent instead.)
Anyway, I understand your frustration. When I bought my 100-400L back in October, the thought of it getting updated soon was definitely heavy on my mind. However, I needed it, and I had not heard any reliable rumours (an oxymoron, I know) yet, so I decided to pull the trigger. Now I have tons of great photos from my San Diego trip to show for it, even if one of the February 2010 announcements turns out to be a 100-400L II. One can always sit on the sideline and wait for a better lens/camera to be announced, but we are all here because we like to take photographs, and not only collecting gear, right?
P.S. What do I consider reliable rumours at this point?
24-70L IS
14-24/2.8L
