According to a Neogaf user who allegedly has inside information, Crackdown 3 is in development and is set to release on Xbox One during 2016. He states that a deal was agreed between Microsoft and developers Cloudgine, who was co-founded by David Jones, for development of the game which is currently codenamed “Nimbus”. Jones was the founder of the studio which previously developed the Crackdown games Realtime Worlds so there could certainly be truth to this rumour. However he says that there is unlikely to be an announcement regarding Crackdown 3 anytime soon, especially at E3 as the game is a 2016 title.

“You will get Crackdown 3, unlikely announcement at E3 this year, as it is a 2016 release date. I can tell you that there is a deal with Microsoft and Cloudgine for the project (codenamed Nimbus) that was struck back last year.”

It has been rumoured that the next Crackdown game is in development, especially after the Crackdown orb appeared during Microsoft’s Xbox One reveal which would suggest that Crackdown 3 is highly likely.
