They've already done a WoW Console joke, they did that last year, keep up with things people! lol

And @ Sqrl, they already did that a couple of years ago with WarCraft 3:
A new hero class was announced on March 31st 1 minute before midnight with no date posted so everyone saw it on April 1st, and that was the announcement of the Goblin Tinker. Everyone assumed it was a joke, and tons of people made custom models of it for download assuming we'd never see the real thing. What do you know, a month later a patch comes out that adds the Goblin Tinker as a neutral hero! Everyone was like "WTF!? LOL!"
