@strider92: Couple things:
1. Recent events in Superior have made it so Ock doesn't have access to Peter's Memories anymore.
2. While ock has shown he can depower IM with prep...Iron Man has Shown he can beat Spidey both with and without prep.
3. Since Ultron was baiting a trap...the credibility of the feat shutting them down is brought into question. It was pretty much a Rope-a-Dope.
4. While it's true Tony won't be really trying to Hurt "Peter"...He can sttill use that prep time to develop "non-lethal" measures. He can simply "Spoof" The Spider-Sense again.
