Thanks to the secret ninja teams of CSC Corporate Domains, we now know that Square Enix has registered a domain linking to a possible new entry in the Legacy of Kain series. The domain in question, WarForNosgoth.com, makes direct reference to the world, and a possible conclusion to the events set in motion in the previous entry in the series Legacy of Kain: Defiance.
There hasn't been any confirmation from Square Enix yet, but considering last week's reveal of a new IP, Murder: Soul Sacrifice, from its domain name registration, this may well be the long-awaited return of Kain.
As for ZeniMax, no word has been given if wolfenstein-spiel.com is related to the well-known grandaddy FPS game. That being said, there aren't a whole lot of other Wolfensteins that the domain might be referring to.
