This keeps getting funnier. This is apparently from a post he made 6 months ago at Whedonesque (It was reposted, and I don't know where to look for the original so I can't swear to the accuracy.)
Speaking of Dark Horse Comics, they are starting a new Buffy comic, and as I understand it, it will take place after the end of Buffy and Angel and be canon in the Buffy world. And I understand it that way 'cause I'M WRITING IT. I'm kicking off the book with a four issue arc that finds Buffy -- you guessed it -- living in Italy with The Immortal. (Scott [Allie] -- don't be mad I spoiled the announcement -- saying it means I have to finish it.) Then I'll be overseeing the book more closely, to make sure it remains true. Gonna be interesting.
And then he goes on to say that it might tie into the you-know-who-movie.
The "season 8" bit seems to be coming from Dark Horse's PR, not Whedon, so I think it might be a mistake to focus on that wording too much.
