According to one article, broadcast insiders stated that Tablo was sorting out his busy schedule for his upcoming comeback reportedly set for this fall, and ultimately made the decision to stay on the show only up until the end of this year.
In response, a YG Entertainment rep told Star News on the 14th, "We haven't discussed their possible leave, so we don't know why there are rumors that they will stay on the show only up until the end of this year... We've never even talked about how long they will stay on the program or when they will leave... There was no such talk, so they will continue to do the show. As long as there are no changes made to the show itself, they will keep appearing on it."
So you can let out a sigh of relief as Tablo and Haru seem to be in it for the long run!
