Considering there's separate trailers for both discs as well as the whole set, it makes me wonder if the two discs will be available separately in addition to as a set (most likely the case digitally).
A lot of stuff I'm not really surprised by. I figured Elmo's Ducks would probably be there (a few years ago Toughpigs did an article on that being the most-viewed clip on their official YouTube channel, though that honor has likely gone to a different clip by now). It's great that the mystery box segment is finally seeing an official home video release. I'm also glad that the Sherlock Hemlock clip on here (and we don't know that that's the only one) is one that hasn't yet been released on video (considering that before this there's only been two Sherlock Hemlock segments on physical disc). Ditto for the Monsterpiece Theater sketch known for inclusion is one that hasn't been released on physical media (it was in an episode in the digital Sesame Street Classics Vol. 2, which I am at a loss on whether to count; I'd probably count that release more if it was a specially-assembled digital compilation of inserts ).
Most of the street stories that have been confirmed in articles are shown in the trailer (the vulture.com article mentions Snuffy's debut which is the only confirmed one we don't get a glimpse of). I'm not surprised by anything we now know. I figured we'd either get The Count's noble prize or Numericon, have been hoping we don't get both since both have been released on DVD in expanded forms (I was hoping for Numericon a little over the other, it'd be good to see that story as aired as opposed to with all the extra footage, but I can see the Jerry Nelson tribute being more important).
If the two discs are sold separately in addition to together, it would be great to know which one sells better (ditto for the digital release).
The Shout! releases have been having special YouTube reviews by kids, I think they've all gone online before the releases came out (there's been a review for the upcoming Dance Party a few weeks ago, and I think Awesome Alphabet Collection had a review a month before it was released). It would be interesting to see if they have a kid review this set, not because it could give us confirmation on a few more segments (okay, that's one of the reasons, but actually not my main reason for curiosity),but it would be interesting to see if they have a kid review this more collectors-based release. Interesting to see a kids take on various things that are more for fans like us.
