The next Sesame release, which will also be the first release for 2019, will be called Celebrating Family, which will include a number of fairly recent family-focused episodes, such as the introduction of Rudy (which I figured would be included once I saw the title, before I read the description), plus a full-hour episode, the Elmo's World: Families episode, and a Sesame Studios short.
It would have been great if, as a bonus, they included the storyarc with Miles being adopted (or at least his first appearance), the episode where Gabbi is born, and the episodes where Gina adopts Marco. Not to mention the home video A New Baby in My House (though they haven't included any out-of-print VHS releases as bonus videos). But this does sound like an exciting release.
