That's quite interesting, leaving aside all the monopoly arguments, I think this has potential to being very beneficial to all blizzard games, and so to us.
It looks like Kotick will be leaving after the transition so that's a great start. My dream is that this all somehow leads to the full Overwatch PvE campaign coming back onto the table again (given that their attempts to provide long-term replay ability without doing the work seem to be floundering now, there's a chance right?)
It'll definitely be interesting to see how MS treats Blizz's ongoing IPs. There's definitely opportunity to improve things there with Diablo 4 not keeping people's attention and OW2... being OW2.
