Hopefully this means better working conditions for ABK employees under Xbox.
I also think ABK getting sold was inevitable - Kotick wanted out after all the controversy so it wasn't a matter of if it was being sold, but to who.
The only real candidates that would be interested were the Big Three console manufacturers, Tencent and the Saudi sovereign wealth fund. Maybe throw in Amazon or Apple as alternative courtiers, were they considering a big move into the spaces ABK occupied. Google might've been an interesting one, but they're still licking their wounds after a bruising and expense foray into gaming, so I suspect they won't touch the industry with a ten foot barge pole for the longest time.
Sony going for ABK would get even more regulatory scrutiny than Xbox, given their vastly stronger market position making them better poised to profitably keep ABK games off Xbox and Nintendo systems in a way that just isn't feasible for Microsoft to do.
Nintendo simply don't do acquisitions that big, so probably weren't interested.
And I don't think the other two would be good owners from the perspective of ABK employees or consumers.
Apple would be a non-starter with regulators unless they agreed to spinoff King. Meanwhile, Blizzard + Activision would lose money hand over fist exclusively on Apple devices, which is what would happen because you can count on one hand the number of apps and services Apple supports on non-Apple hardware.
And Amazon would dilute the quality of the products and treat employees like garbage.
I hate consolidation, but holistically, if a sale must happen, I think Microsoft is probably the most willing and best placed to do it. So I'm not unhappy.
