Blizzard Warlock Tidbit

For all you warlock fanboys out there, here is an awaited tidbit from Blizzard!

Q: Are Infernals and Doom Guards in World of Warcraft?

BI: The two most powerful warlock pets are mighty demons that can barely be controlled by the summoner. The Infernal and Doom Guard can be summoned, but are aggressive against all players when they first appear. In order for the Warlock to control the demon, he must successfully cast the spell Enslave Demon. But these mighty hellspawns will never fully be tamed and can break free of the warlock's spell at any moment.
