Marvel has released the following image this morning.
The only information we have is the creative team and month. The natural assumption is the return of the Fantastic Four (obviously). Another assumption would be the return of the Human Torch.
Honestly, I don't think this necessarily means the return of the Johnny. It might not even mean the return of Reed, Sue and Ben as part of the Fantastic Four. After Spider-Man joined the team and wore a Fantastic Four-ish costume, they got on his case about it being in poor taste. This didn't make a bunch of sense because other teams like the X-Men and Avengers have lost members and didn't disband the team. Then again, the FF have been more about family.
Although, you can argue that the team isn't completely about family as they have had other members like Crystal, She-Hulk, Black Panther and Storm, among others. Perhaps we'll see the current Future Foundation team continue with a different set of four heroes operation as the Fantastic Four. We shall see in November but the fact that Hickman and Epting are involved does make it seem more likely that we'll see some sort of return of the original team. Whether or not that means Johnny is coming back, we'll have to wait and see.
