So far they've found 3 new possible companions:
- Gusting Grimoire (BoP)They speculate that the Gusting Grimoire will be the common pet loot from the upcoming TCG expansion deck (aka: "Floating Spellbook"?), and the Red Panda was datamined from the 5.1 PTR as the reward for an achievement to defeat X legendary wild pets (where X was either specifically named legendaries or a certain number).
- Living Sandling
- Red Panda (BoP)
Unfortunately, the achievement and pet reward never made it into the live release of 5.1, but it could make it into 5.2! There was some mention of "boss pet battles" being considered where players go up against a legendary version of an existing wild pet. So that could be a thing. :P
Things could have changed since the previous datamining, so we'll have to wait and see!
