I must say, the secret ending in FM is worth it! Unfortunately, it's copy protection is unusually enforced, probably because it's new, so cant upload it. you can download here.

Here's my analysis.
1.We see Kairi running down the beach to Sora in a lead-in to a cutscene we saw 9 years ago. The number 1 appears
2.Aqua's walking up to Ansem the Wise in the RoD. The numer 0 appears
3. Everything we saw in Blank Points(which plays automatically at the start of the episode) rewinds with digital video effects. until we reach the ending of the Final Episode in the english version. The number 0.5 appears, stating that this happens between BBS and KH1.
4. Aqua's in the Realm of Darkness looking at her wayfinder. She says a few things that in English dont really mean too much and are predictable except "we will be at the real world again".
5. Boss battle cutscene. The enemies are actually very hard(for this game), but thankfully the established waves dont respawn. The Heartless are here because they always existed.
6.Aqua walks onto a surprising scene: the Castle of Dreams. It apparently already fell to Darkness. Time goes faster in the Realm of Light, so It's probably been years since she was in that world. "A Fragmentary Passage" appears.
7. Mickey's in the RoD. This is probably during KH1. He seems to be looking determinedly at something we dont see.
8. Riku carries Kairi's limp body to the edge of Big Ben in Neverland in KH1.
9. Donald and Goofy are in Traverse Town, looking for Sora.
10. The gang from Twiligh Town-Hayner, Pence, Olette, and Kairi-are staring up at the Old Mansion. This is during KH2, as Kairi never visited them again.
11. Sora's asleep in his pod, watched by DiZ
12. Riku watches from above as Roxas and Xion walk by in Twilight Town's Tram Common.
13. We see the young Xehanort from the beginning on DI's beach, looking out over the ocean. He turns around slowly, morphing into Ansem Seeker of Darkness, then finally Xemnas.
14. Quick flashes of Master Xehanort.
15. Sora sits on the Paupou tree, and is gone miliseconds later, representing his KH1 journey possibly.
16. Same with Ven. Could this mean Ven was moved? Only one who knows the secret of Castle Oblivion could get to him, and so far, only Aqua's qualified to know.
17. "Birth By Sleep: Volume Two".
This is speculation, but what this video teases could possibly be a game that takes place between and over the other KH games with the characters whose povs we havent really seen yet. Or one in which we do play as a primary character with cutaways to others.
What do you think? Other than SA, I mean.
