Celebi V, Keldeo V, Tapu Koko V, Regirock V and Victini V has been revealed at the Champions League 2020 in Tokyo. It has the set symbol sA. These are from the Sword & Shield V5 Starter decks. These decks will release November 29, 2019.
Update: More info and new cards about the Starter V5 Decks have been revealed. You can read it here.
Also worth pointing out these do not contain the V MAX mechanic that will come in future main sets. These V cards really seem to be true to their product name.
