Slayer Calling It Quits After 35 Years?

If this video is to be believed, this is the end of an era. 

Slayer, one of the most recognizable metal bands on earth, are throwing in the towel after 35 years. 

No word yet on why or when exactly but there seems to be at least one last tour in the works. Could it be the Slayer, Lamb of God, Anthrax, Behemoth, Testament tour? That would be a hell of a way to go out.
