Any links to news about the new Specimens?

Has any information been released about the new types of specimens? (btw it's fantastic that new ones have been added!)

After seeing the trailer I'm very interested in reading what the 'Cyst' is all about.

It doesn't seem to like light, but does seem to enjoy raw meat. (maybe it's just really hungover from the night before, and still a little drunk - especially based on how it walks)
