Get on the Danganranpa 2x2 hypetrain.

Just like Hundred Line Last Defense Academy they're holding the cards to their chests and hiding the kino elements of the game until we actually play it. But "Trigger an entirely new scenario with new victims and culprits" mean that this is absolutely Danganronpa 4, and 2x2 is just a cute way to display that as a title, the same as V3 was.
