Uf! I wonder about this. Could they disappear from USF? I wonder what will come out from this purchase? Maybe a new financial agreement or licensing deal? Or would Disney go for the kill, stripping USF from such characters? And with the financial crisis at USF, I wonder what will or might become of them...
They can't, you have nothing to worry about.
BTW, I read that Universal Orlando's profits were actually up for this year. Attendance is down, but they seem to be doing ok.
