I know I saw something about it somewhere else, but I can't remember where. Both USAIGC and AAU hold National Championships each year for lower levels in fun locations, so my guess is that this is just a way for USAG to keep up with some of the competing programs. It will be interesting to see if it actually takes off and how competitive the competition turns out to be.
With the USAIGC National meet, it's really just a matter of what gyms/gymnasts can afford to pay for the meet, travel, accommodations, and all of that stuff so sometimes competition is pretty limited in some levels/age groups. I imagine this will be a lot of the same, but a potentially good opportunity for those who have the chance to take part. I think we'll just need to wait and see how it actually plays out.
