Slayer share teaser video for 'the end' coming this fall

Thrash legends Slayer have issued a rather cryptic teaser video in support of an unspecified fall 2019 endeavor. Concluding the video, the narrator proclaims, "this is the end of the monsters" as the Slayer logo, Nuclear Blast logo, and the text "Fall 2019" appear. You can check it out below. Unless Slayer are putting out a final studio album, which seems highly unlikely, it would seem that an announcement is imminent regarding their purported final North American tour.
