System Of A Down's much-rumored comeback/reunion tour is expected to be announced on Monday, November 29, along with details of several European festival appearances in 2011, including the U.K.'s Download.

When asked by a fan via Twitter if there is any truth to reports that System Of A Down will play next year's Download festival, System bassist Shavo Odadjian replied, "Stay tuned."

OK, we stay tuned...
