It was quite the saga back in 2010. Infinity Ward founders Jason West and Vince Zampella were fired by Activision amid controversy of the two executives talking to another publisher (Electronic Arts).
As it turns out, they were planning to open their own studio, which they did promptly after leaving IW. Hence, the aptly named Respawn Entertainment was born. However, as a couple sources have recently informed Kotaku , West has not been with Respawn since last May. But no drama this time.
Evidently, his departure was "amicable" and he left due to "family issues." It seems he left right around the time their ongoing lawsuit with Activision was settled, which was also in May 2012. Therefore, West hasn't been involved in the development of Respawn's first project, which is set to be published by EA and should be exposed at this year's E3. We're still interested to see that project, although we also wonder where West will turn up next. That mess dominated news headlines for months; it never seemed to go away. Maybe he just got totally sick of the industry…who knows?
