Spoiler for Theory:

So, as extension to my theories up to now, I say that Madoka's "wish", to call it, is going to be exactly what she told Mami: She wants to be useful as a _real_ Magical Girl, out of a feeling of duty and with the intent to truly help people and NOT as a means to an end (doing it for the wish from QB). And by becoming a true MG without the motivation of a selfish wish, she is _really_ going to gain the power to do true miracles.

Spoiler for My thoughts:

That would be a good speculation; maybe the real theme here is Madoka breaking the cycle and becoming a true magical girl, one not limited by Kyubey's rules. So we're gonna ask what means would it have to be? It's fairly easy; Madoka has a natural intent to help people and this, without anything in return. I'm quite positive that once Madoka gains the determination to 'change this world', she will transform from a person full of doubts within herself to a determined person who would rather die than to see others suffer. If my estimation is correct, Madoka becomes a Puella Magi during or after ep.6. Coincidentally, this time in a show from a similar genre was the time that show strayed away from the norms of Mahou Shoujo. If I'm wrong, then maybe the writer really is some kind of sadistic person.
