Blizzard Entertainment's third Worldwide Invitational event in Seoul this weekend is shaping up to be more than just the usual coming together to appreciate the worlds of Warcraft, Starcraft, and Diablo - it looks increasingly likely that the developer will use the event as a platform to announce a new title.

A teasing timeline has appeared on the front page of the Blizzard website, highlighting the studio's past portfolio such as the 1996 release of Diablo, and the early days of Warcraft. Five more games are yet to be put under the spotlight including the all-conquering World of Warcraft - but more importantly, the last title (due to be revealed on Friday/Saturday) has a question mark over it.

Despite official confirmation, it seems highly likely that the title will be Starcraft 2, following reports in the Korean media last month.
