On barnesandnoble.com, you can see not only the cover of the upcoming graphic novel Logan Likes Mary Anne!, but also new covers with Netflix logos for upcoming editions of the first seven BSC books. If the first such editions are published on May 5, maybe the Netflix series will also be available by then.
Amazon.com says an eighth BSC graphic novel, Logan Likes Mary Anne!, by Ann M. Martin and Gale Galligan, will be released on September 1, 2020.
There are already reviews for the upcoming graphic novel Karen's Witch, here and here, for example. You can see the cover for Karen's Roller Skates here.
Here and here I've seen upcoming book covers referring to Netflix. IMDB's cast list for the series doesn't mention the BSC members yet, but it lists actors playing Buddy and Hamilton Barrett, campers and a counselor, and perhaps characters from The Truth about Stacey.
I think that in Caroline Cala's upcoming Best Babysitters Ever series, Kristy's Great Idea inspires three 12-year-old friends to found a babysitting club.
Started a podcast with hubs who is reading the books for the first time. Hope you'll listen and love <3
