My guess is that at Christmas they'll release specific missions that will give out Potara medals instead of Supreme Kai Stones, maybe missions from the Dokkan Event tab, and that's why the announcement says that the medals are obtainable "from Supreme Kai's Trial", and not "in exchange for Supreme Kai Stones". And the fact that Vegito costs only 20 Stones leads me to believe that those missions won't be particularly easy. For most people, at least.
