Of course, it's always possible, (and don't hate me for this folks,) that there actually is no loop to be in. Maybe, just maybe, there's not actually any plans for a Dragon Challenge replacement?
Fun to imagine what could be done in that space of course. But I'm gonna lessen my hope until we get any inside info, an official announcement, or see some walls go up. Sorry to be a debbie downer.
Of course, a bunch of little orange flags all around the coaster footers would be a great sign of something going on. That might get me excited again.
