There are only two divisions (B and A) max per agegroup. It was max 8 teams per division, they expanded to 10. But some divisions have less than 5 teams registered, so they have said they may combine into a single agegroup without divisions. The B division was initially offered to rec programs. The alignments will be likely follow how teams align for the summer: B and A in "B" and AA and above in "A"
