Someone on the battle.net forums noted an interesting fact.
Starcraft was released on April 1st of 1998 (or possibly 1997? April 1st, either awy), and the .999_=1 equation was an April Fool's joke that Blizzard made a few years later.
Put the two together and perhaps it means that there's a Starcraft 2 announcement coming? O_o
And if there's a Starcraft 2 announcement, then the other accompanying announcements could be just as major (D3, WoW:X)? o_O
God I love hype.
