Planned for sometime this year.
I mean, when there's still over 30 titles yet to be announced for released I don't see why going back and redoing stories already released has merit.
At least reconstruction specialists Loose Cannon waited until their entire line was out before going back and redoing old releases.
You can't compare professionals to amateurs. The Loose Cannon people do a great job, but they don't have the resources available that the BBC has.
The reason for the revisitation is simple: the discs being redone were issued years ago, to begin with, and since they came out the people buying the BBC Video releases have become more demanding in what they expect for both picture quality and bonus features. Therefore the ones being redone are those the fans have been demanding to see redone. Talons was pretty sucky when it came to picture and sound.
It's not the first time this has happened. The Key to Time season was reissued in a far superior edition than the original releases. The Five Doctors was reissued in part due to fan demand that the original version be made available on DVD. And Remembrance of the Daleks was also redone.
There are about a dozen other releases I hope -- and in fact, expect -- to see reissued with improved sound quality and extras. In particular any 1960s era stories issued prior to the VidFire process being introduced (Tomb of the Cybermen, for example) I would expect to see reissued.
I don't see what the great sin is in doing this. Maybe I just make too much money (

- take sarcastically) for it to bug me. I'm willing to buy a new edition again if the episode is of interest and the contents are of interest. And if BBC Video down the line manages to figure out how to upconvert these old episodes to high def and start putting out the Blu-Rays, I will probably buy them again, too. It's no different than buying a new edition of a book.
I'm not a fan of double dipping within a few months or a year of a release (see, for example, Sin City and Watchmen) but once a few years pass, as far as I'm concerned the statute of limitations comes into effect. The Five Doctors, for example, was first released to DVD back around 1999 or 2000. Talons was issued back in either 2003 or 2004. Do the math.
Steve Roberts is quoted by DWIN.org as saying BBC Video plans to keep issuing classic series DVDs up until the 50th anniversary in November 2013. There aren't that many available stories, so there will be more reissues between now and then.
I only wish the BBC would buy out Universal's claim on the TV movie so we could finally get that made available in Region 1.
