So we have two moon knight related articles, one one Comic Book Resources:

and an interview with IGN:

Looks like there's plans involving moon knight for a good long time, sounds like he'll be in the Shadowland event, and if he really is a member of the Secret Avengers the Heroic Age might just be the Age of the Moon Knight(not to be confused with the murderous silent hill inspired Age of Khonshu).
