If you answered, "I have no idea and that ... that makes me ... so ANGRY!! RAWWWWWRGGGH!! HULK SMASH!" before jumping through a solid pane of glass and running into the woods, you're technically incorrect (but I'm giving you points for creativity).
Everyone else will just have to wait until September 2 to find out what sort of overarching kismet links these dudes together (but I swear, if it's that fucking Beyonder guy again ... just don't get me started on that guy).
I won't even attempt a guess, but my hope is for a Super Smash Bros.-style adventure game. Four player competitive puzzle solving?
I don't have any idea how that would work, but I'd buy a copy.
