If they have one I may go for that rather than the Disney Water Parks.
I was thinking much the same thing, but didn't want to be the first to say it on the site.
The company could be spin off in a way that still allowed Busch significant management influence. (Sort of how Lego spun off Legoland to Merlin w/o much change at the top in the Legoland parks.)
Also, with the parks' increasing emphasis on the Sesame Street franchise, that's a obvious conflict with the (over-21) Busch brand. That doesn't mean one or the other needs to go... it's just always seemed, to me, at least, like there was a better balance point there to be found. Perhaps this is a step toward that, too.
If that happens to Sea World, I would recommend prayers for the animal population.
