It appears that Activision has forcefully removed two Senior Staff members from Infinity Ward today according to the SEC report filing this morning. This was following accusations by Activision of contract breaches and insubordination. 

"The matter is expected to involve the departure of key personnel and litigation," read the filing. "At present, the Company does not expect this matter to have a material impact on the Company."

The two were Studio Heads, chief creative officer Vince Zampella and CTO Jason West, who both worked on the critically acclaimed Modern Warfare series. It appears that the two had a meeting with Activision but haven't been seen by the Infinity Ward staff since. At the moment, Infinity Ward is creating DLC for Modern Warfare 2 and supposdely has an entirely new IP in the works. More on this story as it develops.
