“There has been talk [of a new album],” frontman Serj Tankian told Rolling Stone earlier this year, “and we are going to play this tour, come back and we’re going to see where we are.
“If we have songs that work for System, if I have them and Daron [Malakian, guitar] has them. The openness is there to work together, but we haven’t made any particular plans that we can announce.”
