Okay, so it's not really like you can just go purchase half of the Universal Orlando Resort - but the Blackstone Group has decided to trigger its sale option, and is now offering its stake in the resort to partner NBC Universal for an undisclosed amount.
Both companies have partially owned the resort for some time now. NBC Universal now has three months to either accept Blackstone's offer or the entire property could go onto the market. That outcome could have potentially hazardous results such as the loss of key intellectual properties, but many doubt it will come to that.
There's a lot of twists and turns in the details of the possible outcomes, and the Orlando Sentinel has a good synopsis of that in this article. The resort is quick to point out that it has had several owners during its life, and has remained strong as ever - quite literally with the smash success that is the Wizarding World of Harry Potter.
