Any info on the new reapers?

I'm usually duoing reapers with a friend, so going 6 skulls@level tends to be quite painful. We did do a Trial by fire (which is really easy for its level) at six skulls and encountered two new types "Despair" and Vegneance" (a prime candidate for a name change right there). Vegneance did us in pretty harshly and we had to cake to continue. The Despair had a cool aura but didn't accomplish anything.

By the release notes I had the impression that there would be additional reaper types even on lower difficulty settings. I haven't seen any of those; what's the status with low skull reapers?
