200-400 VR does not equal prime lens sharpness?

Sometimes I wonder just how far some of you go in examining images.
For me it is quite simple - if my images are good enough they sell
and with the 200/400 I've sold plenty. I am not into getting out a
magnifying glass or specialist testing and I guess I am probably like
most users, amateur or pro; if it pleases me it pleases me, full
stop. I'll say here and now that even if the 300mm and 400mm are
sharper, it wouldn't affect my choice of lens because I photograph
motorsport and the zoom allows me to take shots that otherwise would
simply just not be possible. A quarter turn with a flick of the wrist
as the car comes towards me changes from 400mm to 200mm and I can
follow the car in and choose the best shot later. Similarly I use the
70/200, both lenses sometimes with the TC14X but not the 17 or 20.
The latter is so slow to focus that it is useless. No, I read these
threads sometimes for interest's sake but that only. It doesn't
change my opinion of my 200/400 which I consider the best purchase I
have ever made.

Well, I don't think anyone is saying the 200-400VR sucks. Between 200-400 it doesn't leave me wanting for any prime. BUT it can't be pushed beyond 400mm using TC's like a prime can. Those that don't need to use TC's should be VERY happy with this lens. But those like me, that were hoping we had a path to quality 500mm using a TC have been disappointed. At least I am.
