So I read through the news posts, and laughed at
one of the April's fools. Then I noticed that the "game" on that site actually worked, and gave different "authentication" codes. These codes included some random stuff such as Pi's value, but also a date 11.02.2005, which is
the release date of WoW in EU.
One of the codes were the date of the topic, 15052012, and I suspect something (involving Blizzard) is going to happen then. It seems a little early for MoP release, so what do
you think it might be?
