Just off the cuff, I will say after Disney bought Marvel it really didn't make much sense to have two comic companies tied directly to the studio. We were all set to announce our first project and I woke up the next morning and heard the news same time as everyone else did. Our announcement was put on hold indefinitely.
What happened after that will be tackled eventually, either in a non-fictional account or ala a comic about Hollywood which will include events that may or may not have been inspired by real events.
As far as I know my former partner is still with Disney and has mentioned Kingdom a few times since I left. Haven't spoken with him in over two years so not quite sure what the status may be currently.
