Infinity Ward recently re-negotiated its contract with Activision, hints of a new IP were floated about. Now comes word from Xbox World 360 magazine (via CVG) that the Call of Duty 1, 2 and 4 developer is "definitely" working on a new sci-fi shooter.
Although it's hard to imagine the COD series going into space or through multi-dimensional rifts, there is precedence for a sci-fi COD6 rumor. Call Of Duty sequel or original IP, either way, is this the new project they're "excited to be working on?" Until official confirmation (next week, perhaps?), we're definitely filing this under rumor.
