As for the team of background characters, they are going to have input on what the characters are going to be like. Part of the perk is that they go to the RT office and actually discuss the designs with Monty himself.

I always figured that the fan characters were going to be put in from a contest. Of course, that's because Monty said something about a future contest, so that may still happen. Maybe. It could. I can't help but wonder what kinda rules he'll set for it.
