Okay. You're entitled to your opinion.
Here's an idea I just thought up: What if Avengers 3 is in 2017 instead of 2018? I remember reading here
that Marvel plans to culminate everything in 2017. If that's still the plan, then maybe Phase 3 will just be three films: two of which are side stories (Ant-Man, Doctor Stange) and one that continues directly from A2 (Planet Hulk). This would work in the case of the Avengers being so broken at the end of A2 they wouldn't want to do phase 3 films for Cap, Thor, or Iron Man and would just jump right back into Avengers after a year break.
I don't think it'll happen that way, just a crazy idea I thought of.
