Wow, this certainly came out of nowhere! I've been a bit out of the loop over the last few days, so I'm curious as to the source of the rumor. Not trying to impugn anyone's credibility in any way, I just like to track these rumors back to their original source, when possible.
If true, this sounds pretty great. The SLOP trailers/teasers haven't done really anything for me, but IP aside, if we're getting a big dark ride, filled with AAs, and trackless (!) to boot, then I'll be incredibly thrilled. I do think this is the sort of ride that USF could use more than IOA, but I'll take 'em where I can get 'em!
