Well, the story has been leaked and I won't ruin it here until after the issue is on the stands, but here is how it could have ended to appease everyone....
1) Instead of trying to kill spidey, Doc could have simply stripped him of his powers.
2) This leaves Peter a chance at a normal life, but needing a replacement, fast.
3) In comes Miguel O'Hara.
4) Peter then has to go through the steps of making sure future Spidey knows the rogues gallery thereby becoming not unlike Oracle. It also would have given Peter a chance to improve his science background and, while building up to the moment he becomes Spidey again, works out some new toys for his arsenal.
5) One of the gallery discovers Miguel is from the future and sends him back leaving Peter no choice but to become Spidey again, now relying on gadgets to give him back what he once had via the accident.
This all could have been a year long event resulting in O'Hara returning at the end to realize there are now TWO Spidey's. Eventually Miguel would name himself something else, but stay a part of the Spidey Family and, possibly, move on to a permanent Avengers role.
Instead, we get another step, IMO, in the wrong direction. I will wait to pass final judgment until I see (I'm not buying it) the end of issue #1 of Superior.
