This is really just a case of clarification from the man at the top of the Douglas fir, but we can take it as the final word on a series of Twin Peaks rumours. ie. – the perennial but dodgy ones about the series somehow coming back.
Here's what David Lynch himself has had to say about the upcoming Twin Peaks Blu-rays and any possibility of new episodes. He was addressing the the Tel Aviv Cinemateque, just yesterday, via the magic of Skype:
Rumours are just that. Rumours are rumours. There's always been rumours about things and there's no real truth to it. I don't where these rumours come from, but I think they were based on some misunderstandings of what's going on.
It's true that there will be a new Blu-ray of Twin Peaks, of the pilot, the first season, the second season. And there will be some special things on that Blu-ray that haven't been seen before. That's about all I can say.
So, in short: the new discs will contain unseen business, including but maybe not limited to the recently-shot material.
As Lynch made no mention of Fire Walk With Me, I guess we can expect the many deleted scenes from that film won't be included. It would seem odd for them to appear in this set without the movie itself, and doesn't sound like an agreement the publishers are likely to have made.
Thanks to Welcome to Twin Peaks for the word and these two, brief videos of Lynch making the statement above.
