As far as I see, I can only see a solution about this whole stuff. You see, they told us that the new Superior Spiderman will have new powers like retractable talons in hands and toes. That automatically should discard Peter, Peter/Ock or Ock as the new Spiderman. I mean, just because somebody switch brains with you, it doesn't mean your body will be modified. I mean, Dr Doom swapped bodies with Reed Richards once, and that didn't make Mr Fantastic's body to gain new powers apart of his classic elasticity. They said that there won't be clues about this new Superior Spiderman's identity in "ASM #700", but the talon's stuff makes suspect on Miguel O'Hara somehow.
In my opinion, with the encouragement of his Uncle Ben's spirit, Octopus (Peter) will escape from prision with some "allies" to try to stop Peter (Octopus). There will be a physical battle which Peter (Ock) will at first win, possibly with the Avengers or other character helping the wrong guy without knowing it; but starting to suspect something is wrong. (Maybe not by the memories, but let's face it, Spidey has too much influence in the Marvel Universe to make an imposter undectectable at everyone's senses).
Then, after another possible "heart attack", his Uncle Ben will give him strength to fight again; and protect Peter's beloved ones from a vengeful Ock. The good guys will probably realized the true in the last moment, and then, both Spidey and Ock will end "comatose" in a mental fight. In this new level, Peter will finally beat Doc Ock and returned to his body just in time to die. Peter returns to his body, but he can no longer be Spiderman after killing someone, even someone as miserable like Ock. So he abandons his role as Spiderman "forever".
You may don't remember it, but this old "switcheroo" already happened to Peter once, just in a different way and in a different reality. Do you remember the last issues of "The Amazing Spider-Man"? (I talk about the REAL one, May "Mayday" Parker, no that jerk of Araña). Fury, the Goblin Queen, kidnapped Peter Parker and they "downloaded" Norman Osborn's mind in his body. Then, May, the spirit of Aunt May, Peter and April (May's clone) had a psychic battle against Norman Osborn inside Peter's brain; which ended with Norman destroyed once again and Peter controlling his body again. So, if Peter could defeat Norman (his greatest enemy) in this situation, why wouldn't he be able to do it with his "third greatest enemy"? After all, Marvel is "recycling" stories from a long time:
- Araña becoming "Spider-Girl" (which I still don't accept).
- In the group called "Bastards of Evil", there's a was a girl named Aftershock who said to be Electro's daughter. But unlike the one from MC2, this one was a fake.
- Flash Thompson as a "military Venom", it sounds VERY similar to the "What If...?" about Venom's symbiote bonding with Punisher instead of Eddie Brock.
- General Ross becoming the Red Hulk, just like in the "What If...?" about him becoming THE original Hulk instead of Bruce Banner.
- A group called "the Revengers", similar to the one from MC2.
Well, what do you think of my suspictions?
