Billie 'to leave Who series two'

Enough is enough, what is the point? There is going to be no continuity in this, and there needs to be for it to survive. BBC have said that she will be leaving at some point in Series 2.
Thats it, have her killed by the Cybermen ... in fact deaths too good for her, she needs to leave the TARDIS mid transport, and she ends up floating in the time streams.
