It seems that some old games may be rising from the dead in the future. Recently it was found out that Square Enix had registered a domain for Legacy of Kain, WarForNosgoth.com. Nosgoth being the realm that the Legacy of Kain series has been held in.
Zenimax also has some secrety stuff going on with Wolfenstein it seems. They registered a domain that is more blatant than the Square Enix domain: wolfenstein-spiel.com.
While neither of these may have any relation to either games, that’s highly unlikely. Just like in JRPG’s, vicious rumors tend to be true.
