Xbox 360: Halo 3 Ending Leaked?

I was going to title this something innocuous like "Halo 3 Secret Boobies Unlock Code Unveiled" or something equally innocent to entice my three 360-owning-friends to click the Play button. But then I thought of the consequences of ruining the biggest game of the year for them...oh, the consequences...(i.e. how I'd never be allowed to borrow that little white toaster off them again)
