I have been waiting to see what manufacturers would come up with to leverage the popularity of DSLRs (Canon 5D, etc.) but with a more professional bent.
Here's a link to a soon-to-be-released camera from Panasonic, the AF100
I love things that DSLRs offer, like low-light capability and shallow depth-of-field, but working with them seems like a hack to me. A huge set of accessories can only approximate standard features of a professional camera. And they cease to be super inexpensive by the time you purchase all of the toys.
The RED Scarlet seems doomed(?) but it held the promise of an incredible sensor in a professional package for real filmmaking.
