I can't wait for EG: Legend of Everfree! Especially its Love Triangle. ;)
So here's what I think will happen; The Main 7 stumbles upon Gaia Everfree and strange things begin to happen. During the camp activities, Flash starts a rivalry with Timber Spruce. I'm guessing the camp counselor and Twilight will have a romantic moment... that's when Gaia attacks.
Now people have been mentioning about nymphs ever since the movie's announcement. I'm thinking the girls find themselves in danger and they are saved by Gaia Everfree. At first they are afraid of her... until Gloriosa and Timber reveal that she is their sister!
A long time ago, the sibling nymphs (Okay many believed nymphs are all girls, no boys, so this becomes a big issue and annoyance to poor Timber) lived in Equestria, spreading...
Hold on. (Watches 5th preview of Legend of Everfree. Glaring at jerk in the limousine)
Okay. I think these nymphs not only have control over nature, but also crystals. For some reason, they were sent to the human world and established Camp Everfree. Unfortunately, while Glory and Timber turned into regular humans, Gaia retained her powers and she had no control over them. So she isolated herself in order to protect everyone, including her siblings. She even allowed them to make up a scary legend in order to protect the campers.
Base on the preview, I'm guessing "Jerky Rich" found out about Gaia and tried to capture her in order to exploit her crystal summoning powers. But you-know-who comes and save the day.
I'm guessing Twilight will bond with Gaia as the two know what's it like to be lonely and to suffer from dark secrets, but together they manage to face their fears and save the camp.
Also, I'm thinking Diamond Tiara would stop her dad from shutting down the Camp by threatening to tell his secret to her mother. Then she, Silver Spoon and the CMC will be excited to go to camp as well.
Hopefully, Flash and Twilight will have a romantic moment in the end. (With their classmates watching from afar) I'm also hoping for Timber and Sunset to be together.
In an epilogue scene, I predict a certain purple alicorn marrying a member of the Royal Guards. ;)
Well, that's all for now. See you guys on October 1. :D
