Well,
as I predicted, spider-Man has joined the FF... if by FF you mean Future Foundation. Marvel Comics has announced an official name change for the world famous Fantastic Four after the sudden, heroic death of their youngest member, Johnny Storm, The Human Torch.* Regular readers know that the Future Foundation has actually been around since
Fantastic Four #579, formed as a group of gifted youth. Throughout Hickman's run thus far, two things have occurred: the FF have invited several gifted and super powered children to live in the Baxter building, and Reed Richards has become determined to guide humanity to a better tomorrow. In issue #579, he gathered a think-tank consisting of his daughter Valeria ,a Valeria-reprogrammed Dragon Man, a clone of the Wizard, Artie, Alex Power, and some other Moloid and Atlantean children the team has taken in.
At first glance, it appeared that it was just going to be Reed teaching the kids, but now, I think the Foundation may become more of a training-in-the-field situation with Spider-Man and other heroes acting as mentors and teammates. I'd put money on She Hulk showing up, as Jennifer Walters made a cameo early in issue #579, when Reed was scolding a group of futurists for having grown old and stodgy, he singled out Jen as an exception. Now that there's no numerical limit on membership, the FF could open its ranks to an unlimited number of heroes. Just Please, PLEASE, no Wolverine!

Its okay, he'll be back...
