At $200 - count me out. We still don't really know much about DC 4 and if I really want more drums $ 200 will buy significant expansions for my BFD and Superior Drummer.
As Leadfoot is having some sucess with Kitcore and Jbridge I may give it another try, I did not install it on my new DAW.
What's the bet Sampletank 3 will weigh in at a similar price point because of the new content. I predict a riot.
