There are three threads on the Star Wars Leaks reddit from someone named "JediPraxis." Each thread covers a different "act" of the movie and they've been up for a few weeks now. Each act breakdown is fairly detailed, though there's a lot of context and connective tissue missing. It's as if his sources are privy to certain footage/stills/info, but not all of it. So there's a decent amount of guessing as well. Anyway, with the latest trailer, Praxis was basically proved to be legit. Most of what's in his breakdowns is in the trailer, and even before then, he was able to provide context for the past two trailers, it's just that no one knew if he was telling the truth or not (even though everything he was saying made sense). That said, I only read the first two acts a few weeks ago but won't be reading the last one. And again, because there's still a decent amount of unknowns in his breakdowns, even the first two acts aren't that spoiled me/us, as there's still a good amount missing / not explained. But I *do* at least feel like know the general story / order of planets visited, etc.
