I've heard the same, and that it takes place after the Romulan homeworld is destroyed and will deal with some of the fall out of that.
The bar was set at ground level with Discovery. Chabon did one of the new "Short Treks" that just came out, with Spock and Number One singing while they were stuck in the rollercoaster turbolift. Meanwhile, no one even bothered thinking about beaming them out with the transporter. That's the lack of logic and common sense that kills it for me.
Since Chabon is also showrunner of Picard, needless to say, I've got low expectations. Maybe if they were back on the Enterprise-E and they had gotten the entire crew back together, it'd be one thing, but ripping off the ideas of Tim Russ' Renegades concept, along with Bryan Fuller's previous pitch... well, I'm betting on storylines that again aren't fully explained and plot holes all over the place.
Add to that the fact they've already said the backstories of the new characters on Picard will be fully explained in the comics/books. As a producer of a television show with a 10-episode first season, that should be fully explained within the show itself. You shouldn't need to buy books to understand what's going on, leading up to the show's premiere. Look at Orville. Within the first episode, we got to meet all the main characters, understand who they were, and what the show was about. That's what a good television writer is supposed to know how to do, for any show on television, not just a science fiction one.
