Sarah Jane Adventures: Series Four

Brilliant news!
There will be a fourth series of the Sarah Jane Adventures.

This is from Doctor Who Magazine Issue 411:
Although we're still a couple of months away from transmission of Series Three, everything is looking positive for the future, as Russell T Davies explains: "While we;re yet to dot the i's and cross the t's, early pre-production work on a fourth series of SJA has begun in earnest. We've had a meeting with all the writers - with some new names in the mix - and storylines are already being prepared. And they're excellent stuff - I think there's some amazing stories yet to be told! We've got huge support from CBBC, which is hugely appreciated, so all being well, we should be able to make an announcement soon - proving what we've always known: Sarah Jane Smith is just unstoppable! But as always, it's a testament to Lis, Tommy, Daniel and Anjil that the programme is held in such high regard both within the BBC, and by the viewing public.

Hooray! What fantastic news!
Although, I do fear that Series Four may be the final series.
Think about what Russell said: "I think there's some amazing stories yet to be told!"
That got me thinking. This show is a bit limited compared to Doctor Who because it's set purely on Earth and so eventually, they are going to run out of stories so unfortunately, I think Series Four will be the end.
