Apple buying Sony would make a lot of sense.
IIRC Sony makes the cameras in the iPhone. Apple would gut Sony's phone division for patents and then they own the cameras in their own devices, much like they do the CPU/GPU. From a vertical integration standpoint, not even looking at gaming, Apple might look at it.
And then of course, the PS5 effectively becomes the new Apple TV.
B/c would be dead, though, since Apple would want to move to an M-based PS6 as soon as possible.
EDIT: And Apple would not have to actually buy Sony. Just buy the movie/music divisions for content, the gaming division for Playstation, and the phone division. Sony makes most of their money off insurance and they'd just become an insurance company.
