Interesting! I'll probably wait until early next year to buy it (I hope it's not super limited) as I have too much to buy between now and the end of the year, but I'm definitely interested in this.
I hate gimmicky complete series packaging, but I don't have any of the season sets yet and that bonus disc is tempting. Especially for the episode of Day By Day. It was a short lived sitcom that ran for two seasons. The dad on that show had some kind of connection to Steven Keaton (I think they were roommates in college or something).
I actually wouldn't mind a DVD release of Day By Day... or at least a best of set that includes the "A Very Brady Episode", where the son on the show (played by C.B. Barnes who would later play Greg Brady in the two theatrical Brady Bunch movies) is obsessed with a Brady Bunch marathon, and has a dream about being on the show as their son "Chuck" with several original cast members returning.
And I'm done rambling for now!
