Reall 10 Secret Levels in MBU for 360?

I just wanted to clear up a discussion going on at the xbox.com forums...By coincidence maybe, on April Fools Day someone posted that on the level Survival of the Fittest if you trap launch high into the air you enter a secret room where it says, congratulations for doing the ultimate launch, and you then receive 10 secret levels that are found under a new category "expert"...I find this hard to believe, and haven't even tried to do it, but more and more people are supporting it, and I want to save everyone the time they will waste trying to do this since it more likely than not is not true. Can an employee please verify this myth as either True or False. Thanks.
