Tim Seeley in his recent interview let slip details about the upcoming crossover.
Been waiting for this. Can't wait to see how all the repercussions of Jackie's actions play out, and just how Sara reacts upon learning the truth (my guess - not pleased).The cool thing is that we're doing a sort of mini-crossover thing with all the Top Cow books. It starts in "Artifacts," goes into "Darkness," then "Witchblade" and then back to "Artifacts." It's called Progeny and deals with what we first started when we did this rebirth of the Top Cow Universe. I'm really happy with how those turned out. We all got to write each others' characters. We got to jam on the stories; Jackie is in "Witchblade" and Sara is in "Artifacts," so it's a cool little story. Then there's two one-offs. One is Sara going back to New York City -- she's been in Chicago since the beginning of my run -- and we structured that as a hardboiled detective story that I've been wanting to do for a while.
All three main Top Cow books have been awesome since Rebirth. And this crossover has me excited.
