Of course, this product has been rumored for ... well, for a long time. Separately confirming a BioWare / LucasArts collaboration and a BioWare MMO project lead to certain obvious conclusions and countless other rumors and leaks seemed to do everything but confirm (and some denied) the project's existence. Though it would appear Riccitiello wasn't quite ready to put a name on that project – it's Portfolio.com connecting those dots – by referencing that this is the game that "people are dying for us to talk to them about" he clearly seems to be pointing to KOTOR.
[Update: We've just spoken with N. Evan Van Zelfden, the writer of the report, who told us that when asked specifically if this game was "KOTOR Online", Riccitiello responded unequivocally, "Yes." So, there you have it – sounds like we can take off our skeptical glasses.]
