The only reasonable priced ones will be VIACOM, CBS, Lionsgate, and maybe they could go for foreign entities but very few have crossover US appeal that Fox already has. They could try for Activision as well.
Fox is overvalued. As for the ones you have mentioned, none of those options are a go. Hasbro is looking to produce their own stuff hints why they looked into buying Dreamworks. Also with toy sales going down makes no sense for Disney to buy a toy company which pushed them into a partnership with Paramount. As for Sony, it is structured in a way where two totally non related entities in Sony Corp holds rights for IPs and the other produces (Sony Music Entertainment holds the rights for 76% of everything Sony owns), Sony Pictures Entertainment does film production etc. They only way to get both is to buy out Sony Corp which is a lot harder now for US agencies to buy Japanese companies compared to the past. Its the same issue they will have with any valuable gaming company based in Japan. They could buy out EA but I would call that a loss for Disney.
