This game is not likely to have anything to do with the current issues, it's probably the rumored Vietnam War based COD 7 from Treyarch, and has been in development since the release of World at War.
That's a common thing with companies that get bought by other companies. When a company buys another company where most of the value of said company is actually its employees, then it is typical to set up a bonus for people who stay for instance the first year (but when large multi-year projects are involved that's likely to be more than just the first year). Mind you this is obviously extra money - a bonus that comes over and above your regular monthly pay.
