BBC Worldwide's Plans for Doctor Who on DVD in 2015

If you want to own the complete series of Classic Doctor Who on DVD then you're pretty much living in cloud cuckoo land. At least, that's the opinion of BBC Worldwide. They have confirmed that the DVD of The Underwater Menace has been officially cancelled. Citing the reasons for this, they stated that it was due to the fact that the company producing the animated versions of the two missing episodes has ceased trading and they do not want to release orphan episodes on their own. 

However, a recent tweet from BBC Worldwide suggested that they still planned to release more Classic Doctor Who in the future.

What is happening? Has the work experience guy who handles their Twitter account noticed that there are still many Hartnell and Troughton stories that remain unreleased little realising that a quick check of the archives will confirm they are currently missing (or at least in the hands of a madman with a box of magnets)?

Anyhow, closer examination suggests that the new 'Classic' Doctor Who DVDs may be a little desperate to say the least.
