In a Gamasutra report, Chris Morris explains that "industry sources say Sledgehammer's Call of Duty will be set in the future and feature, for lack of a better term, space Marines, a very big step for a franchise that has historically based itself on realism."

Originally announced as an action-adventure title, the Sledgehammer game will be a first-person shooter in the franchise according to its website. Whatever the game is, Activision will be investing heavily in it and other Call of Duty titles, according to statements made on its most recent earnings call.

Sledgehammer Games is run by Glen Schofield and Michael Condrey, who both left Electronic Arts and Visceral Games to form Sledgehammer for Activision.
