I’ve heard in the past that Infinity Ward has a less than cordial relationship with Activision. The shit finally hit the fan this morning, though, when two of IW’s top guys took a hike after meeting with the publisher.

At some point yesterday, Vince Zampella and Jason West met with Activision, after which they didn’t return to IW offices. Instead, a bunch of “bouncer-types” came around, presumably to ensure that neither exec would come back to work. By noon today both Zampella and West had updated their LinkedIn profiles to include Infinity Ward as previous experience.

Kotaku also dug up an SEC filing from yesterday that showed Activision had launched an investigation at IW for “insubordination” and “breaches of contract” regarding “two senior employees.” Activision has since confirmed both departures and announced the formation of a special division dedicated to churning out one Call of Duty game every year. Looks like the company will continue to bank on that franchise as a major source of revenue for as long as it can.

You know what’s not a bad way to start a new year? How bout announcing that your latest title has sold more than a billion dollars worth. Yes, Modern Warfare 2 has reached that rare milestone among industry developments, and it’s still going strong.

“There are only a handful of entertainment properties that have ever reached the $1 billion mark,” said Activision CEO Bob Kotick, “which illustrates the power of the Call of Duty franchise and mass appeal of this game.” In case you’ve forgotten the baffling sales statistics, more than half of that billion was made in the first five days the game was available. Utterly insane.

In other new, Avatar (the movie, not the game) broke the billion dollar mark not too long ago, putting the two in a race to beat out Titanic’s $1.8 billion gross and Guitar Hero III‘s $2 billion.
