The Next Doctor
Video Business is a trade publication for producers and distributors of video product, primarily in the US. It's a publication from the same people who publish Variety, the entertainment industry trade paper. I used to work for a distributor, and I still get this electronically - it's always interesting to read to see what the trends are. And sometimes there's cool stuff too! Here's an announcement about "The Next Doctor."
I'll let you know if I find anything else of interest.
The 2008 Christmas special, Doctor Who: The Next Doctor is scheduled to be released on DVD in North America on the 15th of September 2009. Oddly (but not Oodly), this comes approximately six weeks after the scheduled release of recent special Doctor Who: Planet of the Dead (available on the 28 July on DVD and Blu-ray).
The Next Doctor stars David Tennant as the 10th Doctor along with David Morrissey. The DVD has a suggested retail price of $14.98 in the US. This single-disc release will include a 60 minute bonus feature of Doctor Who at the Proms. The usual trailer, sub-titles, Dolby Digital 5.1 are included as well. No word about an audio commentary, but one is assumed to be included.
