I saw a site yesterday with a bunch of videos...if i find it again I'll let you know. Though I think it had the ending but not the boss fight, now that I think about it. So you probably saw that too.
I've seen enough of the game for myself at this point (as have anyone else who's been through this topic), that I'm not going to check out the ending or the boss fight. No sense outright ruining it.
I thought it was neat that the story is written by the guy who wrote the Final Fantasy games from VII onwards (except for IX and XI), as well as the spinoffs (VII: Advent Children, Crisis Core: VII, X-2, etc.) and the Kingdom Hearts games. (I like Final Fantasy VI and IX though, but you can't deny that counts for something.) That would explain the epicness of it, and would have to turn some Square-Enix fanboys' heads.
Oh, and the link to the soundtrack torrent is here:
