Finally, a series (Series 3) of Blake's 7 has been released when originally scheduled. But I can find no information on when Series 4 will be released. I hate to have gotten this far only to have to wait a long time for the final 13 episodes. So - anyone with info on Series 4? These sets should have bee released within 3 months (or less) of each other. Heck, they should have been released in one big set; any fan of the series wants the whole thing.
