Busch Entertainment Corp have said they are going to make a MAJOR announcement Thursday 28th at 11:00 EST. Rumors are that the owners of Seaworld, Discovery Cove, Aquatica and Busch Gardens are to announce some on-site resort hotels, or the possibility of some new attractions?

But from what I'm reading it may be that we are looking at Seaworld China???

We can wait to be corrected, as the live webcast is available here
