Jason West and Vince Zampella, two lead developers at Infinity Ward, met with Activision earlier today. Then they seemed to disappear and "bouncer-types" showed up at the studio. This Activision filing might explain why.

"The Company is concluding an internal human resources inquiry into breaches of contract and insubordination by two senior employees at Infinity Ward," Acitivsion states in a filing with the U.S. Securities and Exchange Commission. "This matter is expected to involve the departure of key personnel and litigation. At present, the Company does not expect this matter to have a material impact on the Company."

Activision also adds that it will be releasing another Call of Duty game this year. That game is believed to be developed Treyarch.

According to West's Facebook and Linked In pages, he is currently no longer working for Infinity Ward.
