One thing I've realized is that while one press release confirms Ladybug Picnic, that doesn't mean it's the original. Of course it probably is - the article refers to it as a classic, though the article writer could have been informed of the songs inclusion without knowing it was remade and assumed it was the original.
I've been hoping/expecting we'd get at least one thing from all 50 seasons (will we get anything from the upcoming 50th season?), but it currently doesn't say. It just says that we'll get segments from all five decades of the show. They could skip some seasons. I definitely don't expect street stories from all 49-50 seasons, but maybe I'll be pleasantly surprised. But I was thinking maybe it could have material from every season but some seasons get skipped over on certain discs. Like disc 1 could skip inserts from seasons 4, 5, 9, 18, 32, 41, and 43, while disc 2 could have street stories from those seasons but leave out street stories from seasons 6, 11, 23, and 38 (and yeah, the season numbers are picked at random, doesn't reflect what I want or expect).
