My prediction...
Someone with a preconceived notion will find something in this episode to confirm their beliefs and go "SEE? I told you guys! I am so right about all of this!"
But I'll predict something just to be wrong. ;p Kyoko will call a truce with Madoka and Sayaka, deciding that it is more important to find out what the real deal is before continuing. As a selfish person by nature, she likes having all the information at her disposal so she can make a decision that best benefits herself.
We'll find out what Kyoko's wish was, but not really what her power is (leading to speculation about what her power is).
Sayaka will say something like, "This new revelation scares me, but I knew there would be risks going in. I'll just have to fight that much harder."
And this is going to be an episode of much revelations.
Oh, and they still won't clarify what a wish can do, nor if it can revive Mami.
