Those are just partial work in progress preliminary lists. For the boys the latest is there's going to be up to 14 teams in boys03-01 due to the overwhelming demand and the fact that some clubs had multiple same age teams accepted and they don't want them to play each other.
When the lists are posted on the DSL website then the picture will be clearer but there still could be some adjustments after that. When it's all said and done I think DSL will be similar to CSL by having multiple former age split Academy teams: Rsc, Pat's, strikers, etc
