i think it's because the DO optics cost a lot to research, and develop...they probably cost too much to research and develop, as it seems like that line is just a big failure in my opinion....that's why there aren't any new DO lenses coming out now...
That's true... R&D. It was the first DO lens. I guess the 70-300 DO is the only other one developed since. I know one photographer who uses it and it appears to work well. I don't know anyone shooting with the 400/4 DO, but have seen some really good images out of it.
It's interesting that none of the recent/current super tele "Mark II"s use DO, but still manage to be more compact and lighter than their predecessors.

...An entry level shooter would do well to go with the 70
-200 f/2.8L IS and a 2x converter over the 400 f/5.6L...
This really wasn't a very good option with the original 70-200/2.8 IS and the Mark II 2X.... the image quality just wasn't there (the zoom worked pretty well with the 1.4X II though).
It's only since the 2XIII and Mark II lens have become available that the combo is fairly competitive with the prime in terms of image quality. On the other hand, the zoom plus the teleconverter will set you back about $3000... more than double the price of the prime without IS, but probably still slightly better image quality.
