SAN DIEGO -- In 2008, Belgian brewer InBev -- the parent company of SeaWorld -- bought Anheuser Busch for $52 billion but what they wanted was Budweiser, not the theme parks.

"That's not a natural fit for InBev. They never expressed any interest in holding on to those properties," said Erick Bruvold with the San Diego Institute for Policy Research.

For months there has been talk about InBev selling off the parks, and many theme park insiders have been blogging about everything from possible park closures to naming potential buyers like Disney.

10News contacted Disney officials, who said they would not comment on "rumor or speculation."

But there is another indication that a sale is in the works, as InBev reportedly wants to raise $7 billion through asset sales by the end of 2010.

Bruvold said a sale would not be such a bad idea for San Diego.

"That doesn't mean anything bad for San Diego. I'm thinking it'll mean good things for San Diego as things move forward," said Bruvold.

Locally, SeaWorld employs up to 3,000, and about 4 million people visit the park each year.

Experts believe a sale could mean more revenue for the region as a whole.

"If we get synergies they'll do co-marketing between theme parks in Southern California, so people will come from Los Angeles, stay for a couple of days and spend extra time at SeaWorld," said Bruvold.

Bruvold said another upside would be having a new owner with new ideas.

"One thing true about theme parks is there needs to be investments in attractions on a yearly basis," Bruvold said. "So it is likely InBev will continue and if the price is right we'll see a new owner at SeaWorld."

InBev did not return phone calls from 10News seeking comment.
