I've been thinking of what kinds of releases would be cool for Warner to release. It'd be cool if there was some sort of "Sesame Street Milestone" collection, focusing on episodes and/ or street scenes that broke new grounds or had very big changes. It would also be cool if there was a one or two-disc release featuring street scenes, stories, and inserts in which the adults don't believe in Mr. Snuffleupagus, from his first appearance in 1971 to the episode where they finally saw him. It'd be great to see the street scenes where Maria, Gordon, and Linda decide to believe that he exists.
Another cool idea would be a release of every 100th episode. Episodes 100, 200, 300, and so on... I wonder if any hundreadth episodes were in the middle of any storylines.
Some character-based sets would be nice as well. Last night I was fantasizing over the idea of a two-disc Grover set.
