So I'm guessing $1999-$2200 (high side being where the 70-200 is now) I think making these same priced where one gets you constant aperture while the other gets you longer focal range is a good trade.
I suspect your prices are wishful thinking.
Take a look at prices for the 1+ year old Nikon 80-400mm lens, and then add $300.

Plainsman said:Your figuring would be correct a few years ago but now we have the Tamron 160-600 (which BTW is very good up to 500mm) and two Sigmas arriving before the Canon.
No, Canon will have to factor down their pricing expectations on this one for sales to get some early traction.

100-400L II at 400mm and f/5.6 upresed 50% compared to Tamron 150-600 at 600mm and f/6.3.
100-400L II + 1.4x TC III at 560mm and f/8 compared to Tamron 150-600 at 600mm and f/8.
My prediction as that both would be a near tie, except the Canon will have less CA and faster focusing on the first test.
my prediction is that the first comparison would put the tamron far ahead for total detail, 200mm is an insane amount to make up for, the tamron would have to pale even compared to a coke bottle for that to be true
now in the second case maybe it would be about a tie???? who knows or even better?
Results are mixed, see for yourself:

The Tamron loses a lot of quality from 500mm to 600mm.

I found that focal lengths of 176 to 178mm focus at 0.31 magnification when focused at a distance of 0.98m.
