On BlizzCon, you got a unique mount if you signed up for a dish service before BlizzCon began.
Well, you have to give a **** about the game to want the mount, and to get the mount you had to sign a 2 year contact with (I think it was) DishNetwork for a new service....how much of that contact do you think Blizz got?
Enough to make the effort profitable, that's for sure.
WotLK.....$40 a pop....sold out across America....nuf said.
...and then there's the Collectable Trading Card Game based on WoW (OMG, go to e-bay and search "Spectral Tiger")....and a Miniatures game...commercials on the main WoW web site....
