Just saw the Disney Parks Blog that released concept art this morning: http://disneyparks.disney.go.com/blo...rack-at-epcot/
To be quite honest, I'm not a fan! Sure it looks cool, but this doesn't look anything like testing ground like the old one did, and isn't that the whole point of the ride? I understand the ride is subject to changes especially with a new sponsor, and the changes certainly fit into future world, but I just don't think keeps the storyline they want.
I'll just have to wait and see! It's Disney, and it'll probably end up winning me over in the end anyway!
