No news yet on the UK releases but the Complete Series 7 DVD / Blu-Ray is expected in the United States on 24th September. I assume it will be in British shops on the 23rd (DVDs always being released on a Monday).
If previous years are anything to go by, the series soundtrack might well be out the same day.
And Amazon.com are advertising a Complete Nu Who Blu-Ray boxed collection, along with a Universal Remote Control Sonic Screwdriver, all for $314.98.
A UK version is promised.
