A special charity episode with David Tennant and Billie Piper just aired in Britain, and is available online for a little while. (Though so far, I can’t get it to play. I assume that’s a heavy load, rather them blocking it for non-UK viewers.)
This looks vaguely familiar: Cybus Corporation.
I’ve just ordered the 9th Doctor boxset (the one with all the special features). At just under $100 (including postage) from Amazon UK, it’s substantially cheaper than the (almost exhorbitant) $150 asking price in Australia, and I should get it a week or two before the AU release.
