Vince Zampella confirmed that Jason West has left Respawn Entertainment in an official statement released this evening:
Jason has left Respawn to take care of some family issues. We have worked together on some amazing accomplishments over the years, starting with an early Segasoft project that never shipped. It is sad to see things come to an end, but there are times when change is best for growth, both personally and professionally. I wish Jason the best and send my best wishes to his family. Respawn continues to amaze me, the team here is resilient and talented. E3 will be therapeutic for us, as we finally get to start showing our work again. I know the team was excited about the response we got from just admitting we were going to attend.
According to multiple sources Jason West, founder of Respawn Entertainment along with Vince Zampella, retired some months ago due to family issues. The duo, which were also founders of the behemoth Call of Duty studio Infinity Ward, were currently working on project rumored to be unveiled by E3 this year. Apparently, West has had little to no involvement with the development of the project.
Both Vince and Jason left Infinity Ward in 2010 amidst a flurry of controversy that resulted in a very public legal battle between them and publisher Activision. Their new deal with publisher Electronic Arts is said to also be a first person shooter. Considering the duo has worked on FPS games since 2002's Medal of Honor: Allied Assault, it's unfortunate they won't be working together going forward.
It should be reiterated that sources state that West's retirement has had no effect on the development of Respawn Entertainment's upcoming game. It can't be understated though, that any project would be worse off without West's involvement.
