I myself haven't seen it even on Equestria Daily yet. So it obviously might be a fake. But everyone who knows about it seems to believe this list enough, so I don't know. But I'd say these synopses sound very trustworthy to me and most of them make sense. So I really don't know.

A HUGE SPOILER ALERT!!!!

Fluttershy's brother's name is Brash Buck! And she's ashamed for him. Twilight, Shining Armor, Applejack and Big Mac will try to help them to get along.

And another interesting thing; The pony who's singing "I am just a pony" song is a famous singer and Sweetie Belle's musical teacher named "Harrowing Harmony".

Synopsis to the season finale: "Starlight Glimmer reveals she found a time traveling artifact in the mountains and changes history by stopping Rainbow Dash from performing her first Sonic Rainboom that lead the Mane 6 to getting their cutie marks. The last 5 minutes of part 1 and most of part 2 will focus on an alternate present where Sunset Shimmer is an Alicorn princess living in Canterlot with her own Mane 6. Twilight Sparkle, who never passed the entrance exam to Celestia's school for Gifted Unicorns and is Sunset's assistant, still remebers the entire regular present."

If this is going to be true, we can look forward to it. Though Sunset will appear only in alternate reality, what makes rather a negative impression on me and doesn't seem to have much of logic...

I only mentioned these most interesting synopses here.
