Heh, I haven't been keeping that up to date with this attraction but I've gone through all the plans and construction updates this morning and it suddenly reminded me of a drawing for a floorless roller coaster I did for this very site back 8 years ago when I was only a wee lad in 2005.
Looks like I went a little overboard by adding a complete section up the hill and through the woods but there are funnily enough a lot of similarities too. I wish they went a bit further with The Smiler in the end though, and properly embedded it into the landscape like Nemesis is.
This plan came with a much wider refurbishment to X-Sector, moving Oblivion's shop the the large empty space under its lift hill, opening room for another flat ride and a path along the ancient fort battlements up the hill towards the flag tower and to a new 'land'; the reopening of 'Coaster Corner' primarily filled with large indoor attractions. Here there is a hint of my drawing of that area which included a 'Tower of Terror' ride (with the towers half buried into the ground to get the height) themed to look as if they're part of the ruins themselves.
Anyway though some of you imagineery type peeps might like that. Will be interesting to see now what happens in this area in the future. I doubt the two coasters will be going anywhere for quite some time.
