If someone was to tell the exact plan for KI you wouldn't believe it. I have seen it happen over and over. I can remember a post about Italian Job Stunt Track the night before the press release and no one got it. I can remember coming home after the announcement at the park and people was still arguing that it wasn't what it was going to be.
Then there was Tomb Raider, Screamscape posted the plans for it in full detail and people still didn't accept that. They thought it was a coaster till the day they got on it.
