Regarding the Gotham Central: Soft Targets trade paperback, here's an update from Greg Rucka via his message board:
"I thought it was to be released this year, as well, so I'm afraid I'm as confused as you are. There is a third trade scheduled, as far as I know, so it should be coming soon. The trade ISN'T being called Soft Targets, however--it's combining both the Soft Targets and Unresolved storylines, so I believe the title is--wait for it--
Soft Targets is issues #12-15; Unresolved is issues #19-22--I don't know if the issues in between would be in there, too. That Greg is as confused as we are is interesting ... doesn't seem like good news. No way of telling if that title is a joke or not, either. If it is, that's pretty clever.
