Explaining my thoughts a bit:

 Spoiler

Madoka never decided on her wish. She'll most likely wish her back next episode, especially with a title like that. That is, assuming that would be possible, Kyuubey hasn't exactly said anything about wish limitations, he actually said it could be anything, even something miraculous. That's my thought on it, anyway. There are many scenes shown with all three girls in their magic outfits in the opening and such, and it doesn't seem likely she'll be killed off this early.

Dude, I totally understand how you feel. I totally didn't see that coming.

God damn. Her head was ripped clean off, then the thing started gnawing at her body...

 Spoiler

It was actually a lot more tame than I thought it'd be, but I believe Urobuchi said something about the show not having anything that shouldn't be shown to kids (hence the censored kill).

Edit: This is in an interview:

 Spoiler

• Mami knows mechanism of the world to certain degree, so her part is a guide to Madoka and Sayaka.
  
• Madoka and Sayaka will follows the way Mami lead, but at certain point they might choose their own paths.

And the episode title could be interpreted as "the differences between magic and miracles" or something, rather than magic and miracles in conjunction with one another. Oh well, we'll see.
