The talk event preceeded the autograph session with a special appearance by Suzuki Tatsuhisa, the voice of Makoto who was also at the event for Beyond the Boundary stage. Comments found on internet during the event report that Suzuki said "See you again next summer" when he left (I might add, in Makoto's voice) helping fans to build higher hopes for the second season to be aired next summer.
This board on display at the event confirms the second volume of High Speed, the light novel that the Free! anime was based on, is in production adding to the possibility of the second season.
