It is true. I promise you.
watch the doctor who xmas next time trailer. donna says "sometimes when im with u i dont know wats right or wrong any more" then there a guy with a bazooka, sontaran, then the doctor at a balcony. then theres a scene change to the doctor replying "its better that way". inbetween the scene change something flies across the screen. watch it in fast motion, then pause it. u will see either 3 screens
one with white stuff [a dalek]
one with a greenish thing [davros]
one with nothing [nothing]
