MLS2

Does anyone have any more information on MLS2? I am trying to find information online but it's pretty sparse. I assume they will be their own league but how much of a geographical reach will it be? It seems a lot of EA teams will move up to MLS2. Will this have any rhyme or reason, like promotion or relegation or is everything just getting more stupid and complicated and spreading out the talent even more?

Can you play high school soccer and play MLS2?

thanks!
