As I said in the other thread we have going on this (located here:
http://www.disboards.com/showthread.php?t=1885129), I think its highly likely that InBev will sell the parks. Even before the sale was agreed upon, they had already made it clear they intended to sell off "non-core assets."
The actual profit from the parks is just a tiny drop in the bucket compared to the overall profit of the company (I heard something in the range of less than 10%, but I can't recall off the top of my head.) Really an insignificant amount to a HUGE beverage company like the combined A-B & InBev will be.
I find it /extremely/ unlikely that Disney will buy the parks for any reason. It's not how Disney generally does business (have you EVER heard of them buying and operating an established park?). If they had wanted to, they easily could have picked up the parks years ago when Harcourt was desperate to sell them. Additionally, I don't see Disney having ANY interest in the parks in Texas, Pennsylvania, and Virginia. Nor in the BG in Tampa. It would cost them too much to build up a /Disney/ infrastructure in those areas. And the simple fact that Disney likes to have their own little interconnected chunk of inescapable property would make their acquisition of the Sea World parks, miles from their compound, rather unlikely in Orlando (and California, for that matter). And personally, that's fine with me. I don't want to see Mickey Mouse decorating all the walls at Sea World.
People bring up Blackstone, but I'm not so sure about that. They run small-time parks.. maybe they're a big deal in Europe, but I've never even HEARD of most of the parks they run. Sea World is a much more global name, with an extremely high standard. I'd hate to see the parks fall backwards to that roadside attraction / sideshow sort of thing.
I'm putting my bets on Nakheel. They already have an established relationship with Busch Entertainment and they have plenty of money to spend.. plus, they are all about the high quality (to the point of insane amounts of luxury in some of their hotels and projects!) And while they're primarily focused on development in Dubai, they also have extended their reach to places like New York, London, and Thailand via hotels and resorts. AND, they have marine conservation / sustainability projects already established as well.
So, my guess is Nakheel. But time will tell.
There's a lot of discussion on the other thread (linked above).
