Video on DSLRs question

Current generations of DSLR that do video, have very poor focusing mechanisms while shooting. You can flip up the mirror and get a quick focus at the expense of seeing a black screen for a second or two, or there is the Contract detect which is very slow, at least on subjects that are moving.
(correct me on any of these points if I'm mistaken)

Camcorders I'm guessing use contrast detect algorithms to work their autofocus, and have done so for a long time, and they very usable even with moving subjects.

So what's holding up the development of camcorder like speed autofocusing systems on DSLRs?

Interchangeable lens system for photos. They'd have to design a whole new lens system for continuous AF in video mode.
