According to Canon new lens upgrades tend to sell better than their replacements. 100 macro IS L and the new 70-200 f/2.8 mrk. ii are - correctly - used as examples. And they were both much more expensive than the lenses they replaced.
It's like car performance. You can get x amount of horsepower for say 500 bucks, but to get another 100 HP, it'll caost you say $2000 and then it just gets worse from there. You have a situation where the current, soon to be old, versions are spectactular to begin with, but also cost a pretty penny. You are going to see a lot of people simply not buying the new lenses for two big reasons. One, the new "further in the stratophere prices", especially in this economy and two, the fore mentioned insane quality of the currently owned models.
