We've known about this for some time now, but no topic as of yet. It started with mystery big-size track showing up at B&M's track plant in Ohio, and ended up being used on this. http://rcdb.com/m/id4224.htm If the current stats are correct, "Unknown" will be the tallest Diving Machine in the world, and propably the tallest Floorless coaster in the world as well. We know that it's going to be red, making this the 6th tallest red coaster in the world (behind Steel Dragon 2000, Eejanaika, Moonsault Scramble, Diamondback and one of the Mr. Freeze models). To get things in perspective for the British members, it will be four inches taller than PMBO. To further elongate this post with pointless facts, it will be the tallest coaster in China, snagging the title from Dive Coaster in Chimelong Paradise. And, as the "Unknown" Mega-Lite and Fireball, the two other coasters at the new park opening in 2009, are in progress (thanks, roomraider), chances are that this has progressed pretty far. Luckily, we've just got a Chinese member, and I hope he and Gavin and anyone else can shed some light on this. Now discuss.
