Blizzard today showed us the BlizzCon 2023 program which contains a brand new World of Warcraft mount!
The mount seems to be an elemental that will be available to players in World of Warcraft with “more details to be revealed” at BlizzCon.
BlizzCon 2023 will be livestreamed free of charge, so this may be a mount you either get from buying the new expansion or there will be a purchasable bundle that includes goodies in all games that was usually bundled up with the Virtual Ticket.
