Here's a secret - when I finally okayed the clone saga, I told Danny Fingeroth to build a backdoor into it. I said that I wanted to be able to bring Peter back as the real deal. But I didn't tell Danny everything. I believe that both comic book creators and comic book fans are a cowardly and superstitious lot. While the fans claim they want change, they tend to react negatively to it. So do most creators! With this in mind, I later updated Mark Gruenwald on our plans for the clone saga. Mark was my second-in-command, and the logical guy to succeed me. He and I agreed that Peter was the real guy, but that we would let the Spider-team try to convince the readers otherwise. If the Spider-creators succeeded, they would love the idea of the old switcheroo. If they failed, they'd be soooo harry that they had a backdoor. Either way, the readers were guaranteed a great story with a lot of unexpected twists.
Our plan was to structure the clone saga like a three-act play. Act One would climax at or around Amazing #400 - when we revealed that Pete was the clone and Ben was the real guy. Act Two would last around three months and follow Ben's adventures. In Act Three, Peter would triumphantly return as the one, true Spider-Man. Mark and I were hoping the Spider-crew could make Ben a viable character during his turn in the spotlight, and we planned to star Ben in his own monthly title after Peter returned. It was kind of like what I had already done with Thor and Thunderstrike - two very different titles based on a single concept. Of course, our plan went into the trash the day I got fired, and Mark wasn't picked to succeed me.
I think editorial eventually lost control of the story, and the marketing department took charge. Instead of moving along at a brisk pace, the story was stretched farther and farther out.
