Don't make the mistake of assuming that because a lens like this is well outside the budget of many people, that it won't sell well within its intended market segment.
We're talking about a fairly specialised lens here.
Having the 400mm focal length a speed faster than f/5.6 is a seriously expensive exercise.
Currently, the only way to do that with Canon's current offerings is to buy a 300/2.8L IS and 1.4x TC, or a 400/4 DO IS, or a 400/2.8L IS, with all of those options being very expensive.
Even the price difference between a 300/4 and 300/2.8 is staggering.
