In the latest DLC for DJMAX Respect, Supersonic was just added to the game.
At the end of the music video, there's a nice little message that honors the late Panamaman (one of the main concept artists on S4 League who passed away last year as some of you know)
There was also a trophy for watching the Music Video in its entirety.

Makes me happy they put something like this in here, considering Korean S4 League also recently shut down.
