Okay, the big word has been out. The next world of warcraft expansion, named Mists of Pandaria will feature a pet combat system! I will look forward to epic battles between companions, such as Speedy the Turtle versus Spring Rabbit. Or wait: Alliance Balloon versus Box!
And you will be able to play a panda(ren). So the next expansion we shall all play Panda's staring at boxes and balloons.
(( Hindsight: Neither are combat-pets ))
