I'm also curious what the anti-trust laws say about this. Microsoft is already a gargantouan company, its kinda scary. Theyre doing good stuff in the PC gaming space right now because of Phil Spencer, I suppose, but imagine the next boss is an arse that pushes Xbox exclusivity for everything, once again? Not great.
Although having ActiBlizz games on Steam might be nice, but thats probably gonna take a while, I reckon.
Regarding Kotick, I also think he'll probably stay for a while and eventually leave once everything is migrated over.
