A tweet by George Broussard suggests another four employees have parted ways with Infinity Ward in the continuing exodus from the Call of Duty developer since last month's dismissal of studio heads Vince Zampella and Jason West. George tweets: "4 more people leave Infinity Ward today. Near 50% of dev staff. ETA till IW closure? Activision earnings report in a week" (thanks Edge Online). George is not the only one expressing the public opinion that Infinity Ward's future is in doubt, as Gamasutra quotes Janco Partners analyst Mike Hickey opining: "We expect Infinity Ward studio will be essentially closed after their next map pack release, with development work on Modern Warfare 3 spread between two studios not historically tied to the franchise."
