Yeah, that announcement really is a nice and unexpected surprise. This version of WNMHGB, and the blooper reel, were the only remaining things I've seen from that period that have not been officially released. This is a very exciting development, and a great Christmas present for the fans.
Of course, my dream release would be one with the original bumpers, etc...similar to the Twilight Zone Definitive Collection. I love sitting down and watching that. Its as close as I'll ever get to see the program as initially aired.
