Delixe: Not entirely. The chances are Kotick informed the major shareholders this move was happening, he likely has their backing as all shareholders care about is profits. If Kotick has convinced them this is the best course of action for Activision then his job is likely safe. If of course this is all true which remains to be seen.
Firing the IW heads in an attempt to extinguish the fires he most likely started is one thing. But acting illegally by not paying the whole company - killing any reason they have left to want to stay there - is another. The chances of Kotick's influence not being the root cause is next to nil. He's spelled out that much himself.
Even if shareholders agreed to this form of damage control, it doesn't mean they don't recognise where the real problem lies. At this rate Activision is on a mission to burn itself out completely. It's raking it in now, but most can see where it's going, and it's not up.
PoSSeSSeDCoW: I'm fairly sure that royalties are royalties earned, whether or not you stay at the company. You'd have to look at the contract, but even if it said, as a condition of employment, that royalties earned would only occur when the employee was at the company, it would still be possible that a court would rule in the employee's favor, as Activision lies in a relative position of power.
Well, the royalties have already been earned. They just haven't been paid. If it's contractual then Activision might be able to cease paying royalties to people who have left the company. But only in cases where the revenue was taken from sales made after their departure.
What they make while they work there is owed to them no matter how long Kotick stalls. Which is why the heads are still in a position to pursue their royalties and why the Kotaku story doesn't ring entirely true to me. They'd just wind up with more people departing IW and more lawsuits.
