IGN's rumor mill is running again as their UbiSoft E3 lineup seems to have an addition that is missing from everybody else's list (or the official list sent out by UbiSoft for that matter). IGN's Ubi Soft E3 list includes the following on what seems to be a new add-on for the tactical shooter: "Tom Clancy's Rainbow Six 3 Athena Sword: Looks like the PC is getting a new expansion for the latest in the series. Fun all around!". After Worthplaying contacted UbiSoft, they said "We don't have anything additional to announce about R63 PC at this point", which doesn't mean its not true though.
