According to information obtained from an anonymous source from the English blog VG247, it seems that Infinity Ward will not develop the third installment of the series of Call of Duty: Modern Warfare. This is because it seems the team is focusing on something totally new, reliable, therefore, Modern Warfare 3 in the hands of a few other house developer.

While Treyarch would be working on a new Call of Duty probably set during the Vietnam War, the upcoming Modern Warfare, but it could be entrusted to Sledghammer Games (ex-Visceral Glen Schofield and Michael Condrey) or an unspecified identified development team in Canada.

For now everything is in the field of pure speculation and gossip: we will inform you if they were to emerge news.
