I'm excited to read 52. I picked up the first few volumes after burning through Gotham Central, but then other stuff took priority, as is the way with comics. As a big Renee Montoya fan, I would love to get all the post 52 question stuff, too. As well as the post 52 Batwoman stuff. Scanning Wikipedia entires gave me the impression that those stories are spread all over the place. Minis, crossovers, guest appearances here and there, etc. I did find one post 52 mini collected called The Five Books of Blood. Again, I bought it but have yet to read it. It's written by Rucka and features the (Renee) Question.
