Yep, I've read what everyone has, that S9 is a given, but will be shorter. I didn't know that it was gonna be set in the future lives of the Scoobies, though. That should be interesting!
Past that? Doubtful, s'what my gut says, unless they're just little stories that go back and fill in some of the detail from the past. Which I would SO be reading. Joss ought to do something like that, y'know? Start before the beginning, tell the stories that fell in between seasons. For one, I would love to see Buffy and Merrick, and for two, I would love to see what happened between S6 & S7, then again from S7 to S8. Or heck, here's an idea: Faith's story. Again, I'd be buying the hell out of that.
But anyway, I was just talking about this with a friend the other day, we're both big Buffy fans and both have been devouring S8 as soon as it drops, and wondering what Joss' plans are for the rest of the season, and for S9. Much as I hate the idea, though, part of me feels like Joss is carefully drawing things to their inevitable conclusion. Which is... y'know... sad. 🙁
