Brack says that the idea for the first neutral race actually was rooted in the Goblins for Cataclysm, since the Goblins would have made an excellent neutral race, but the team was adamant about giving the Alliance a more sinister race to play. The Goblins for the Horde filled the whimsical role nicely.
The Pet Battle system coming with Mists of Pandaria is going to require a lot of tuning, according to Brack. The feel of the system is going to be much more "rock, papers, scissors" than "all-powerful rare pet wins the fight," giving a lot of hope to collectors out there who want to use some of the more esoteric companions in battle without having to always pull out the best pet.
Finally, Brack made an important point about the "expansions every year" comment and goal of the development team. Brack explains that the concept is nice but not something feasible in the present time and that Blizzard has not been successful with rapidly turning out content. Cataclysm, it turns out, took longer to develop than any other expansion.
