It appears there is no new stuff with Namor for the November solicits.
He might appear on the last page of the Avengers issue for that month, since the Phoenix is allegedly arriving. But to be honest, I have zero hopes anything good will come out of this story line for Namor. With Cap, She-Hulk and Black Panther already named as getting the Phoenix Force, I think there's nothing but more awfulness in Namor's future. At least we'll get some pretty art out of it.
And then there's is this cover.
