Straight from Newsarama:
Ironheart #1 will now come out November 28 – two weeks later than originally solicited. The second issue of Ironheart will be pushed back five weeks to January 16, off of December 12.
With this, Luciano Vecchio has been added to Ironheart #2 alongside originally-solicited series artist Kevin Libranda.
Marvel has not given a reason for these changes.
Hopefully this new artist will help speed things along so that the series can debut ASAP so that our girl Riri can get her chance to shine!
