Not announced yet as far as I know. Believe it likely it will be free. Free valet service at VWL and BWV is not a "perk" given to us out of the kindness of Disney's heart. Part of the members' dues at those resorts go towards paying for valet services, including the employee costs. Thus it is "free" simply because you are already paying for it in your dues. Likely BCV will be the same.
