Two more Marvel NOW! teasers released today hint that the Invincible Iron Man writer will take over the books at the launch of the new initiative.
"Extended" and "Family", the two teasers read.
Mark Bagley is expected to join Fraction on Fantastic Four and Mike Allred will seemingly illustrate FF.
Jonathan Hickman - who will be writing Avengers and New Avengers - is currently working on an extended run on the two series.
He announced that he was going to end his work on them earlier in the year.
Fantastic Four and FF will relaunch in November.
