The interesting thing is, that Bungie is well known for one thing: Halo
And that is the one thing Activision won't get with Bungie because the Halo IP is owned by Microsoft
What i want to say is, Activision is well aware that just the name of the Studio has a value of its own even without their main-IP, but they seem to ignore that fact with Infinity Ward.
...and lets hope for Bungie they negotiated a time-frame for Bonus payments 
“It appeared that there had even been demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. And only yesterday, he reflected, it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it.”
- George Orwell, ‘1984’
