You might be onto something there...
Daleks, Cybermen, Sontarans, Weeping Angels and other returnees are probably all in storage just waiting to be dusted off and used again, which is probably a lot cheaper than creating something from scratch.
And haven't we heard whispers of budget issues on SERIES FIVE?
(Budget issues drive everything Dr Who has ever done. It's the reason when we see aliens a lot of the time they're wearing masks and only the leader ever takes off his helmet to reveal the complex make up/headpeace underneath, like the Sontaarans, Sycorax, Judoon etc)
