Among still shooters, the need for those kinds of cameras comes from those who have made a transition to video shooter for HDTV programming but also need to provide images to magazines such as National Geographic which requires high def for its broadcasting and demands hi-res for its print repro.

A whole different category of cameras will more affordably take care of on-line publications that want stills and video of the same event for their e-magazines.

I think to a great extent it boils down to hedging bets against Murphy's Law, which has always guaranteed me that at the moment of best light and most compeling image interest, I'll frequently have the "other" camera in front of my eye.
