Theoretically if every state had a championship you would end up with 300 teams with the current 6 qualifying from each state (assuming no overlap in qualifying awards). Team distribution means this isn't a great method anytime soon and there will need to be a way to handle international teams (Canada is 3 or 4 additional regions?) but when FIRST eventually gets their district system in place everywhere it still allows for a Championship event similar to the current one.

I would look at how FTC currently works to get an idea of how FRC qualifying may eventually be handled. Depending on the number of slots given to a state it's not enough to win your state championship, you have to be the alliance captain of the winning alliance to get the invitation.

How is FLL done?
