I think the first podcast episode was just a holiday teaser. Developing and producing good content, and booking guests who have some kind of profile actually takes a lot of time. In comparison the Obamas' Spotify deal was announced in June 2019 and they released their first episode in July 2020, more than a year later. So I think M&H will probably be putting out content this winter.
The 40 people were all over social media at the time. A lot of them celebs (Sarah Paulson, Stacy Abrams, Gabrielle Union, Ciara, Sofia Carson, Hilary Clinton, Adele, Stella McCartney, and Amanda Gorman etc.)
I can’t name them all off the top of my head but typing 40x40 into insta or Twitter should give you that answer. A lot of ordinary people were also participating with the initiative through Linkedin. Archwell did a mini follow up on 40x40:

But I think this initiative should get another follow up and maybe that’s coming.
With Netflix they have announced they are working on two things.- Harry’s sports doc called Heart of Invictus (profits from the series go to Invictus), Meghan an animated kids show named Pearl. Both things were announced this year so will probably be released 2-3 years from now.
