V&U will still be around for another year or so. Bleeding viewers, and bleeding talents. They will go the Tsunderia wave by announcing some new wave or some new talent or thing but they will crash and burn after losing a ton of support. The talents there if smart might grow enough and gather enough of a fanbase that when they decide to finally leave. I feel like what happened yesterday may have gotten them enough outrage that they lose more views than they will gain.
