Only to see he can't handle it and sees Otto's birth thus making him disappear and lose a grip on his 31 memories that he has left.
So I believe that when Peter Parker does come back in Superior Spider-man #31 (cover below) he will be half Peter Parker and half Doc Ock or Peter Parker has control of the body but Doc Ock is like how Pete is now, a ghost in the mind.
I think Otto will realize that his Parker memories are gone or altered by his own memories and he will try to purge himself of his Ock memories that he feels are unnecessary. A small silver of Parker's influence will use the opportunity to purge some important Ock memories in the process. Ghost Ock and Ghost Peter will be on a similar "playing field". A battle will ensue between them and they will both be destroyed in the process. Leaving the amnesiac Peter for Amazing Spider-Man 1.
If I guessed right I'm sure my post will be deleted (like when I was correct about Ghost Peter resurfacing).
