World Of Warcraft: New Hunter Pets

Eyonix chimes in with a bit of Intel about outlands and new pets for hunters:

We do plan to make additional pet types available to the Hunter in Outlands, and of course over time, do plan to improve upon the availability of unique pet abilities. More information on this subject will become available as we move closer to release.

Operation Dwarf-wipe, (as it's called internally) will likely just happen over night, without warning. Also, our programmers are attempting to figure out a way to wipe dwarves from all online games -- so that we can preserve the notion of internet consistency when the great purge begins.
