While there are not much news of substance these days concerning the upcoming season of Doctor Who, this should change soon because the series is expected to debut around Easter time (fingers crossed) in the UK.
However, there are a few rumours running around.
Life, Doctor Who and Combom reports that the Daleks may be in the season finale and that they will film the episode at Stonehenge.
Also, there are rumours that we could see the Cybermen from this Universe as well as the Cybermen from Pete's World (parallel Universe).
River Song may also be travelling with the Doctor for a few episodes.
