To insure that Batman runs monthly, Didio popped in the short "Grotesk" storyline... Its just giving Morrison and Kubert the ability to stay monthly without tremendous delays.
As far as I know, aside from last month's issue, Dini is focused on Detective Comics... Williams I think is just going to pick up as soon as he can.
So it's just because both creative teams aren't able to write a monthly book?
I know DC is screwy with their TPB system, but have they said how it will be affected for these books?
When it comes down to Dini, I think they were looking to give this new writer a spin, so they just slid his story in there. I don't think it was an issue of Dini not being able to keep up to pace..
I thought Dini was still on, but Williams III wasn't able to draw the rest of it because he had to do Seven Soldiers #1. I'm guessing he's catching up by doing some of the remaining issues, hopefully.
