Since version 5.0, the mall's mounts can indicate the general content of the theme of the next version. Version 5.0 introduced the mount Steel Shattered Sky Beast, and a few months later Blizzard announced that the next version was the King of Draenor, and the mount launch matched the next version.
The same applies to version 7.0, the Secret Blade Leopard mount introduced in version 6.0, which fits the 7.0 version of the Surama map.
Before the launch of 9.0, players already know that the next version must be the Shadow World, because in the 8.0 version, Blizzard's two mounts, the Sylvian Divine Wanderer and the Cunning Fox Demon, both represent the Blazing Blue Fairy Field of the Shadow World.
The content of the next version can be seen from the introduction of the mount, so when Blizzard announced two years ago that the next version was shadowy, players were not overly surprised. The next version is the Guardian Dragon version, which is more or less wrong, as last Christmas promotion, Blizzard introduced the Dragon Pack. According to the experience of previous versions, the gift package launched this time is actually a harbinger of the arrival of the next version.
According to the well-known mmo forum bigwig of the foreign service, he has a partner who works in Blizzard, and according to his partner, the next version is the dragon version, and there will be a new continent (similar to the Broken Islands), known as Gala carlos. The name of the new version is most likely "Ashes of Galacarlos". A new class tinker will be introduced, with three specializations and one tank healing output.
However, 9.2 is also going live soon, and as the last minor version of 9.0, the news of 10.0 should be out soon. But 10.0 is definitely back in Azeroth.
