"We are going off on a pathfinding journey to aim the end of new horizon. This is not a graduation nor retirement, but a new challenge." -- As the comment says, those three will continue being a part of EXILE, but will not appear on EXILE's stages as the performers.
Regarding their future activities, Matsumoto wrote that he would establish "Matsu-gumi" in Gekidan EXILE, and further expand his activities as a performer, mainly on stage plays.
