LucasArts' and BioWare's long-awaited, much-discussed joint development project -- widely speculated to be an MMO set in the Star Wars universe circa BioWare's own Knights of the Old Republic -- will be revealed to the press October 21, according to an invitation sent out to media outlets including Gamasutra.

It is likely that the official announcement will come shortly after the October 21 press reveal held at LucasArts' San Francisco offices; events of this nature are frequently subject to a media embargo.

The postcard, which proclaims "The wait is over" and promises "the official unveiling of the game that's been rumored about for years," makes no explicit reference to Star Wars. It is branded with the LucasArts and BioWare logos and depicts floating robots and hooded figures in futuristic interior locations reminiscent of the sci-fi franchise.

The alleged existence of a KOTOR-themed MMO is considered one of the industry's worst-kept secrets, with BioWare parent Electronic Arts' CEO John Riccitiello essentially confirming the title's existence.

Riccitiello called the BioWare/LucasArts effort "quite possibly the most anticipated game, full stop, for the industry," before acknowledging it as a KOTOR MMO.

Development of the joint project is being handled at BioWare's Austin studio, created specifically for MMO development.
