It sounds ridiculous, but I can just see them doing it. Reminds me when they advertised Smiler as the 'Worlds First 14 Looping Roller Coaster' because it won't ever lose that title but it always will be, obviously they'll be coasters with more inversions but they can keep those tag lines because of how its phrased. I'm hoping it's not like that though, but didn't they advertise I'm A Celeb as a World's First too?
