Well, based on the average household income in the largest market for such goods, US$1000 has always been that magical line separating mass market and niche market.
Remember all the fanfare when the original Digital Rebel/300D came out, breaking that $1000 barrier for the first time?
We should be glad there are as many L lenses in the $1000-$1500 range!
Of course, some predict China and India will take over as the largest markets in the near future. Given the average household income there, demand for lenses over $1000 may continue to diminish.

So, let's treasure what we have....

P.S. There is always rental for the occasional users. Near where I am, one can rent the 400/2.8L for less than $150/weekend. I'm sure something similar exists where you live (or there is always online rentals). If you are ready to spend $3000 (it sounds like you are), you can have it for 1 weekend every season for 5 years.
First of all, I'm not raving about the 70-200 Mk II (not yet anyway -- I'm renting it this coming weekend for my sister's wedding). However, it is one lens in your magical price range ($1500 < x < $5000) that has good IQ/AF/IS and can take TCs.
Why is there market for the 70-200 Mk II? Because just about every wedding photographer (and there are a lot of wedding photographers around) has or want one.
People routinely pay thousands of dollars for their wedding photography, but who is going to pay to have little Johnny's soccer game documented? How many people are career motorsports photographers? Wildlife photography is a very small market.
So in the end, without a secondary consumer market (e.g. weddings) to support the photographers, the demand will never be there for the $2000-$5000 lenses.
Sorry to disappoint you....

Are you an economist? Do you work for Canon? All your points are based on what facts? Why does every lens have to be for the pros for it to be considered? If that were the case we would have no EF-S lenses, only Ls. I don't think you realize how many people are into photography and at the hobbiest level. The fact that there are numerous people even interested in the new offerings should clue you in just a little.
How many lenses have been introduced since the DSLR was introduced? How much more expensive are those lenses than the ones they replaced? The price of lenses has gone up significantly and people are still willing to pay for them. Just because YOU don't seem interested in a lens I am suggesting doesn't mean that there is no market for it despite the "numbers" you seem to base your opinion on?
While the wildlife photogs may not be all professionals there are MANY amateur enthusiasts that would be interested in the lenses proposed. Do you know how many people travel to places like Yellowstone, Yosemite, and Africa (Heck we have people here that go on a trip every year just for fun!) to photograph wildlife that will never get paid for a single image they take. And motorsports photogs don't all shoot for money. Spend some time in the photos section here to see what kind of gear folks have, what they are willing to spend, and why they shoot. I think your "facts" may get altered!
