Blizzard has a teaser page online that shows a timeline and each day scrolls through a new splash page for one or two of its old games. Yesterday, Warcraft 1 and 2 were shown. Today, the page shows Diablo.

Last month, CVG reported that the next Blizzard game would be unveiled on May 19th as a StarCraft MMO. At one title a day, we'll get to the question mark on the 19th, so let's see if they're right.

The teaser page lives here.
