I haven't been keeping up with season 3 all that much. I saw a little of this episode, and, I like the idea of alicorn Twilight. As long as it stays that way and there is continuity. Or they at least make something interesting out of it.
I heard that this was supposed to be sort of part 1 of a three part sort of thing, which I'm guessing what happens next will take place in a 2 part season premiere.
