Brian Michael Bendis and artist Oscar Bazaldua will be continuing on Spider-Man into "Marvel Legacy," but they're bringing in both the Sinister Six and the Iron Spider. Announced during the Marvel Cup O' Joe panel at Comic-Con International: San Diego, Spider-Man will be re-numbered to #234 this fall.
According to line editor Nick Lowe, Miles Morales doesn't know who is under the Iron Spider mask. This first "Legacy" arc will, according to the editor, test both Miles' superhero relationships as well as his family ones.
Marvel has not yet revealed when Spider-Man would transition to issue #234 and "Legacy."
