To the first point, it appears their are a few organizations that have good intentions competing with each other. However, there is a lot of money involved.
The Battery fees are high, but there are no team fees. The Battery are limiting teams to 2 tournaments a season, one of which is to be local. I think when it is all said and done, the cost will be comparable.
The fact that every kid will train with the same ball, be dressed the same, head to toe, that coaches will have monthly professional development sessions and the club will have a unified curriculum from top to bottom is appealing (some other clubs also offer that as well, I am sure).
Season tickets to Battery games for the kids is also included. I think the Battery will offer advantages over the long haul.
As for the league, as of Monday, I don't think a decision has been made.
