A listing for Far Cry HD suggests that Ubisoft is thinking of restoring its original 2004 PC-exclusive as an XBLA and PSN game. Spotted by VG Leaks, a listing for the HD version of the original Far Cry was found on Brazil's rating classification board. It's listed as coming to the Xbox 360 and PS3.
Ubisoft is probably hoping to cash in on the franchise with the success of Far Cry 3 and its 80's action-themed DLC, Blood Dragon. However, when asked about the listing, Ubisoft told gave us the ol' "we don't comment on rumors or speculation."
In other words, expect it to be announced in the future.
