Spoiler Slayer

I've received copy of the radio promo for 'Villains'

Announcer: FIRST, ON BUFFY THE SLAYER’S FACED DEATH BEFORE Buffy: Being a slayer doesn’t give me a license to kill. Ann: BUT WHEN A POWERFUL WITCH GOES ON A FULL TILT WARPATH Rack: That girl is running on pure fury. Ann: IT’S LIKE NOTHING YOU’VE EVER SEEN BEFORE Warren: Please stop! Buffy: Willow wait! Willow: It’s done. Ann: YOU CAN’T MISS THIS ALL NEW BUFFY Rack: She’s gonna blow this town apart.

Wanda interview Joss Whedon, and it's up at E! Online. She also has posted a finale game, where you try to get the false finale spoilers. Since the Buffy one has Oz returning to save Willow from herself, I'm thinking that it's likely one of the false ones.

Slayage.com also has the Nicholas Brendon interview where he talks about the end of the series.
