I don't think Sony will sell their media side - it would make no sense. Media makes up over 50% of their revenue stream.
I think if this were to happen, it would likely be Comcast buying Viacom. Viacom has a lot that could be useful to Comcast, such as Paramount Pictures, Nickelodeon Animation, Paramount Animation, Nickelodeon, MTV/VH1/BET, etc.
The only thing really worth a damn out of Paramount Pictures that Universal doesn't already have access to is Mission: Impossible and Star Trek. Nickelodeon Animation has quite a catalog of movies ranging from Spongebob, Hey Arnold, Rugrats and more. Both Spongebob and Rugrats have theatrical releases planned. This would give Universal even more animated content to play with. Hell, maybe they could build another Nickelodeon hotel, but this time the rooms don't suck!

*Looks at thread title*
How did we get to this when topic is Toon Lagoon? Honestly I almost feel like this is a dead topic and should be locked. Throughout most of this thread, especially in recent times, nothing has been added that is actually helping the conversation when it comes to Toon Lagoon. The thing is, TL isn't going anywhere for the time being. We have Potter finishing up and JW Coaster starting construction and an entire new park under way. I don't see a timeline where TL even has permits filed for a replacement before sometime in 2023/24 at the earliest.
