Best Buy recently hosted a World of Warcraft Developer Q&A. Many questions were answered, including some pet-related ones. [source]
- The Baby Shark will eventually be added into the game!
- There won't be a realm first for Pet Battles since it's intended to be more of a casual mini-game.
- Tooltips for wild pets, caged companions, and pets sold on the AH will be updated in patch 5.1.0. The new tooltip will display if you own said pet and if so, how many. Should you already have 3 of that pet, the tooltip text will turn red. [source]
- Mini-pets might drop from raid bosses in the future, but the context in which one drops needs to fit with the content.
