A resposta é "Ainda não".
Você pode ler toda a sinopse, mas tentar elaborar:
The Goblin King finds all the evidence that Otto Octavius is actually in Peter's body so things should begin unraveling for Octavius soon.
And death is one of the most ephemeral aspects of comics, so Peter will be back at some point, the only question is how.
Prior to the Goblin King's discovery, Octavius also discovered a remnant of Peter's personality subtly influencing him, so Otto used a device to purge the last of Peter from his body.
So, it remains to be seen how Peter is going to come back from this... however, it was also revealed that Otto's tomb was empty. Now, I'm speculating but maybe Peter will come back after he "wakes up" in Otto's body.
UPDATE:
O escritor Dan Slott acaba de anunciar que Peter Parker voltará em abril deste ano para 2014 .
Ainda não sabemos como ele retornará embora ...
