Why not a 100-400/4.5-5.6?

I'm not sure what need this fills.

At f/4 it's not a fast lens by any means. So for subject isolation or for indoor shooting of sports events you would be better off with an f/2.8.

For reach, 200mm isn't much. Adding a 2x TC will take it to a 140-200mm lens and it would be f/8. That would mean it is compatible with AF only with the latest bodies, but only them and then with limited AF coverage. Stopping down 1 stop would place you well into diffraction territory so that would be less than optimal for cameras like the D800 and D7000 - even more so for the new crop of 24MP DX cameras. f/8 is also very slow for wildlife shooters who might find it difficult to get the shutter speeds needed.

Finally, it's not cheap particularly given that the pricey lens foot isn't included.

Wouldn't a better performing and updated AF-S 80-400 have served the needs of the likely users better?
