Taken from Screamscape.com announcing an announcment if that makes sense:
It’s OFFICIAL... for the first time ever Halloween Horror Nights will dominate BOTH of the Universal Orlando theme parks each night. This year’s event will be bigger and better than ever before and will change the face of HHN forever. This year’s event will include seven all new mazes, bigger and more intense Scare Zones, the return of the Halloween Parade, special themed shows, hundrededs of Scareactors as well as a the Haunted Corn Field being grown right now. They are promoting it as 360 degree fear, because you will be surrounded on all sides by horror for the night. So far they are only hinting at the theme of the mazes: “Vampire experiences”, “encounters with the undead” and “prisons gone wrong”. Of course we will see Bill and Ted once again, though they didn’t say what stadium they will play in, but I’m hoping for a return to the old Wild West stage. More as we find out!!
