Some more Burbankology, via Bleeding Cool:

Harvey Richards (associate editor) has left, I don't even know which titles he worked on.

Pat McCallum (executive editor, in this case boss to editors, as I understand it) has also left. BC comments:

Bleeding Cool has heard reports that, well, it’s a bit of a sh-tshow in DC editorial of late, with lots of competing power bases, publisher demands in the wake of Batman Damned, and possibly a case of too many cooks. Well here is one fewer.
Rebecca Tay (editor) also seems to have effectively left DC, even if she isn't mentioned in the headline.

Given what Bleeding Cool said here, I guess the earlier big reshuffle this year failed to solve the management problems that DC had…
