To be honest, I feel like the comic staff is just taking whatever chances they can *now* either before or in case somebody fucks up again--someone on staff, some IDW exec, a guy on the street who throws a brick through the wrong window-- and Sega pulls the plug. Again.
The game characters are a given. They're gonna *have* to be around. But making new characters who have potential appeal and can fill the void left by the Archie OCs (let's face it: They're Gone. I don't like it, but they are...) will keep keep the comic going longer, and they'd rather start telling stories about them now, rather than build them up for eventual books only for it to be all for nothing if the door on this comic is closed because someone fucks up again.
