Well, since we got info that, um.. Some Things will happen in season 7, we already know that will happen. What we don't know is what is the Major villain. And the fill-in episodes. I wish that more Oc's will be in the show, for they've already done that with some characters.
I've had a daydream that my character was in an episode. Also, I hope we get to see Gabby and Ember again, and maybe even an episode completely focused on the dragons or Griffins, leaving out the ponies we know and love for that episode, like another slice of life episode.
