At last! According to this post from doctor who news dot net:
Great though it is to get some confirmation on the story’s release – the last ever Classic Series DVD unless more stories are recovered – the explanation is a bit bollocks if you ask me and I still suspect that it will be part of a Box Set along with the two recently recovered Troughton stories – Enemy of the World & Web of Fear. On the plus side, at least we’ve got confirmation that the eps will be animated, probably by that Planet55 lot
In the meantime here’s Lee Johnson’s brilliant artwork mocked up as a Big Finish-style cover to keep us all going!
