Sledgehammer Games was formed in 2009 by ex-Visceral Games and Dead Space developers Glen Schofield and Michael Condrey.  They co-developed Modern Warefare 3 with Infinity Ward, but shall be handling this year’s Call of Duty game all on their own. Treyarch will release their next game in 2015, and then Infinity Ward in 2016.
