As the Modern Warfare 3
It began with former Infinity Ward heads Jason West and Vince Zampella suing Activision in 2009 for wrongful dismissal. Dozens of other former Infinity Ward employees joined this suit, claiming unpaid bonuses and various other grievences. Activision responded by countersuing West and Zampella, and also suing EA for good measure (on the grounds that they illegally snatched the Infinity Ward duo away from Activision).
There are potentially absurd amounts of money at stack in the case. West and Zampella want unpaid royalties from Modern Warfare 2 that could amount to millions of dollars, as well as creative control of the Call of Duty series itself; which is obviously an asset that Activision considers vital.
Meanwhile, Activision fancy getting their hands on $400 million USD from EA.
The trial was due to begin this week, on 23 May, but appears to have been indefinitely delayed for now as the various legal parties organise their cases. If you pop case number SC107041 into the Los Angeles Superior Court database, it reveals that further preliminary hearings in the case are planned for this Friday and 3 June. Beyond that, we’ll just have to wait and see how things develop.
