So in season 3, they now introduce a Hero-Bomber which is based on Riou from Suikoden II:

They also have some icons, poses, music etc. based on Suikoden.
I always thought it would be a no-brainer to include also Suikoden characters as cameos, so this is a welcome change. It is also a nice coincidence that this happened on the game's 23rd birthday. THis doesn't mean anything for the series' future, but at least somebody at Konami remembered that Suikoden existed.
