As confirmed recently by Doctor Who Magazine, the full titles of Series 2 of The Sarah Jane Adventures are as follows
The Last Sontaran by Phil Ford
Day of the Clown by Phil Ford
Secrets of the Stars by Gareth Roberts
The Mark of the Berseker by Joseph Lidster
The Temptation of Sarah Jane Smith by Gareth Roberts
Enemy of the Bane by Phil Ford
As you can see, the series will run to 12 episodes this time – the original adventure Invasion of the Bane – while seen as a pilot – was in fact part of the first production block and is therefore to be considered a "Special". Series 2 of The Sarah Jane Adventures is expected to air on Monday September 29th.
Meanwhile it also seems that early plans to mount two series together – effectively producing series 2 and 3 under one production – were abandoned early on due to CBBC budget constraints. It seems unlikely however that a third series would be passed upon – The Sarah Jane Adventures was the children’s BBC department’s biggest ratings winner for its first run.
