Moving Missing Episode rumors to this thread!
So -- Missing Episodes 2014!
It has now been confirmed by several involved that a commentary track for Marco Polo was completed in November. Which means, obviously, Marco Polo is on the slate. Not surprising at this point.
We also have a report on the weight of missing episodes recovered in Africa -- 3 tons. Though not all of that is Doctor Who, and it is still being painfully cataloged and restored, we're still at where we left off in the season 33 thread -- years away from knowing what could actually be recovered from the old prints.
