Oh, so that’s why.
Overpriced media specialists 2entertain have just announced the release of the five final episodes of the RTD era of Doctor Who in a blu-ray collection ‘Doctor Who: The Specials’.
It’s a classic “penny drops” moment, in the light of the earlier decision to exclude release the first four series only in the latest DVD box set. That said, if the blu-ray release features exclusive extras, there’ll be trouble. Still, jolly good show.
