Edgar gave said in a recent interview with Digital Spy that the script had finally been complete (as they had to incorporate it into the MCU).
Looks like things are on schedule.

Have you read Age Of Ultron 10:AI?
It is a Character study/expanded origin/semi-modern reboot of Hank Pym.
Writer Waid has a likable and interesting take on the character. He found a 'voice' for Pym that really works.
