I looked the season 4 previews and found the sneak previews that got aired at comic con. It first start out that Diamond Terra and her friend was commenting how great the Cutiemark Crusaders, then turn around and mock Scootaloo for having very small wings, and she can't fly. Randomly change to Spikes wakes up in a big city, and finding himself and the main six as power ponies. Superhero going on there. After that the Apple family sings a song they stick together and pinkie is there too. Last thing that happens is Princess Luna has grown jealous over Princess Celestia again, and wants to rule everyone by night. Nightmare Lamoon has returned! Season 4, you are going to be interesting.
