Yes, Aaron and Ribic will be producing Thor: God of Thunder which will start in November. In an interview, Aaron reveals some of his early plans for Thor.
The first story has three components: a flashback to young Thor, present day Thor is space, and a future where King Thor sees things going horribly wrong. A brand-new villain, Gorr the God Butcher will debut and be present for at least the first few arcs of his planned stories.
Aaron says that Thor will initially not interact with his other avenging, or even his Asgardian comrades. Though he did express a strong desire for an appearance by Mangog.
