That's a good take, imo. Nothing wrong with recognizing how a big corp merger might benefit you. I know I seem to side with Sony on all this, but that's really only with specific arguments that I disagree with. For the most part this deal isn't going to affect me at all. I don't play Activision games. Like you, I have all the consoles so I'm not really worried about exclusivity.
Having said that, if this acquisition can magically turn Blizzard into the amazing studio they were years ago then I'll look back and be happy it happened.
