Meh.
People see $68 B and think that's a lot, but in reality inflation means it's not, and furthermore Mega-Corps like M$ have access to free money, so it's even less so a lot. Plus a bunch of other things I don't want to get into.
For the console war, this is a big deal because COD is one of the few games that sells systems for the mass market so if you don't have it on your box then that's a serious negative point. Same if they were to not have FIFA/NBA. Whether they actually make it exclusive, who knows, I'm not totally convinced, but I could perhaps see a COD exclusive/Warzone free for all split. The reason I'm not quite convinced is because I think the revenue it generates has greater importance than the strategic value of denying Sony the title, plus I think it's more important to shut-out the other cloud giants more than continue to haggle over the scraps of a limited console playerbase.
For PC this might be a positive considering how awful ABK's DRM has been, as well as the general awfulness of their launcher, plus it opens up a lot of possibilities for Blizzard IP which has simply been dumped on for years and years by ABK mis-management.
And finally, for me personally, this changes very little except I might finally play through the COD campaigns if they come to gamepass. Otherwise I consider Blizzard more or less dead and I see little hope of it really going back to its glory days, and rest of the studios & IP are w/e.
