We’ve datamined a new texture related to BlizzCon on the Dragonflight Patch 10.1.7 PTR! Likely an unannounced BlizzCon attendance collectible, it looks like it could be a pennant or banner similar to those awarded from the MDI.
These are just textures without models, so it’s not entirely clear what they will be yet.
Both virtual and in-person BlizzCon attendees are traditionally rewarded with extra in-game goodies such as pets, mounts, transmog, and more, for all of their major games.
