Well, from what I keep hearing after poking around with some old sources, the "Ring of Fire" will be the main addition, going into the Golden Kingdom.
I commend the effort of adding flats in areas that need them, especially areas that have removed flat rides. HOWEVER, this is NOT the way to do it. Deja Vu, The Autobahn Re-born, the elephants, and Sky Screamer were tastefully done. Most of them, they are classic rides one expects to find in any theme park.
This ride would have to be very well themed and marketed properly for me to not make fun of Great Adventure for the rest of my life.
