If anyone buys WWE it will be NBC-Universal for one explicit reasons:
Disney isn't in the wrestling game and more to the point, would have to radically redo their scheduling to make room for Raw and Smackdown, assuming they don't just kill Smackdown and NXT due to their nihilistic viewpoint of limiting peoples options to force you to have to endure their anti-life version to get your fix of franchise X.
NBC-Universal meanwhile IS in the wrestling business and save for a brief period in the early 00s, has aired WWE programming ever since the mid-80s on USA Network. It's one of USA Network's flagship shows and one of their programming's cornerstones.
NBC-Universal would jump at the chance to buy the WWE. They know the main players VERY WELL and WWE knows the heads of NBC-Universal very well in return. There would be a seamless transition of ownership and no disruption to the WWE gravy train.
If Disney bought it, hell on Earth would erupt. Best case scenario is that Monday Night Raw is killed because Disney would dump WWE onto ESPN and ESPN currently has Monday Night Football. Also, Disney and ESPN is NOTORIOUS for shuffling crap around the line-up so expect no real permanent schedule of airing of Raw and for the show to go back to being taped to accommodate this. Smackdown will probably become a clipshow to spite Fox and canceled when that contract is up and NXT will be canceled outright.
Disney will then fire everyone involved running the company (even Steph and HHH) and replace them with woke anti-life types. The bread and butter mens division will be decimated and I would not be shocked if Disney puts in people who will be tasked to making WWE a 100% female wrestling company with no men except for a couple of token announcers at that.
Disney's too dangerous to be allowed near the WWE; NBC-Universal might pay less, but for McMahons, they'll at least preserve the company as it is and not completely fuck things up solely to remake it in their own image
