Looks like Infinity Ward rolled over and settled an undisclosed amount to West and Zampella.
Story from DigitalSpy:
Jason West and Vince Zampella's lawsuit against Activision has been settled out of court today (May 31).
An attorney for West and Zampella announced that an agreement has been reached, though the particular details of that settlement are "strictly confidential".
Activision released a short statement regarding the settlement, indicating that some payment was made by the publisher to the former Infinity Ward heads.
"The company does not believe that the incremental one-time charges related to the settlement will result in a material impact on its GAAP or non-GAAP earnings per share outlook for the current quarter or the calendar year, due to stronger-than-expected operating performance in the current quarter," Activision said.
West was reportedly smiling as he exited the court room after the settlement was announced.
The case began in 2010 after West and Zampella were removed from their positions as studio head and president of Call of Duty developer Infinity Ward.
West and Zampella were taking their former publisher to court seeking over $1 billion (£651 million) in damages for unfair dismissal, breach of contract and unpaid royalties on their work.
Activision counter-sued the pair along with publishing rival Electronic Arts for conspiring to "hijack" the Call of Duty franchise.
Electronic Arts issued a statement to Polygon regarding the settlement which read: "Activision's refusal to pay their talent and attempt to blame EA were absurd.
"This settlement is a vindication of Vince and Jason, and the right of creative artists to collect the rewards due for their hard work."
