Do we know how long the current arc is planned to run?
The game probably won't be out until March at the earliest. That's roughly 7 months and 28 more episodes. Then you have to assume at least a year between new games (probably two years with DLC for the first year), so that's another 52-104 episodes for a total of roughly 80-132 episodes from now.
Even if we bank on the low end of 80 episodes, this arc would have been over long before that given how the past four arcs have gone. I can't see a sequel just adding characters from the current arc as the main selling point. I think those characters would be DLC throughout 2018 with a new game focusing on the current cast, DLC and then characters from the arc that follows this current arc, plus maybe more obscure characters from all of the series.
