Activision has registered a handful of Call of Duty domains using names that may or may not signal the future of the IP.
Future appears to be the key word. Call of Duty: Advanced Warfare and Call of Duty: Space Warfare are two of the three titles. The other is Call of Duty: Secret Warfare, according to Superannuation.
Each of the three are registered multiple times to cover possible sequels.
Could these names refer to Sledgehammer Games' action-adventure COD title? Sledgehammer, remember, is the studio set up by EA runaways Glen Schofield and Michael Condrey - them what made Dead Space.
Conversely, they who made Call of Duty - Jason West and Vince Zampella - recently ran back to dealing with EA.
Following the West/Zampella saga, Activision announced a Call of Duty reshuffle. The Sledgehammer action-adventure was confirmed then, although it wasn't clear whether the 2011 date was for that game or for a different, non-Treyarch entry in the series.
