There's some interesting tidbits that came out of his time with the Ghost:
- Sindragosa will be playing a part in Patch 3.3
- We shouldn't expect a hero class in every expansion
- Ghostcrawler was split down the middle on the Death Knight starting at level 55
- Blizzard is interested in buffing up the old world levels to make them more interesting. He listed off (the top of his head): Darkshore, Stonetalon Mountains, and The Barrens.
- Ghostcrawler is responsible for the many varieties of fish in the game. This makes sense.
- Expect an expansion every 18 to 24 months
