WoWInsider had a chance to talk with Tom Chilton (Kalgan) about Patch 3.1 and everything we can expect after that.
*The Argent Tournament will be expanded in Patch 3.2 and will be the biggest feature of the patch
*A new battleground will be added to the game in Patch 3.2
*New dances and druid forms are still in the work
*More hero classes are definitely possible in the future but Blizzard is being very careful about them and don't want to go too far too quickly.
*Dual-spec is a nice idea but Tri-spec most likely won't happen
*Housing is an awesome feature on other MMOs but developers aren't sure if it would be a good thing for WoW in the long run. It might happen in the future but it's definitely not a priority.
