Chuck Greenberg, an owner of the Pelicans, recently completed a deal to buy the Texas Rangers along with MLB legendary pitcher Nolan Ryan. The Rangers recently ended their relationship with the High Class-A team in Bakersfield, CA.
There is no word yet on which high-A team, or if it will be an entirely new team, that will now represent the Braves. One of the best parts about having the Myrtle Beach team was that it extended the Braves territory to the north. Two years ago, the Braves moved their triple-A team from Richmond to Gwinnett, which effectively ended all ties with Virginia. This could, unfortunately, end up having the same affect if they move to the Florida State League.
Both the Carolina League and Florida State League have an even number of teams, so the Braves could end up in either. I expect they have a plan, which will give more definite answers shortly.
