Wondered the same recently. There’s been nary a peep since their initial announcement over the summer. I’d guess this might be a hard sell without some A-lister’s playing the leads (and a suitable venue is available). Perhaps we’ll hear more nearer the holidays when the Arden-helmed Christmas Carol is in town.
Firstly, I looked back at the articles and they said "2023," not specifying Spring or Fall. And with Parade now happening this spring, I think it's pretty safe to assume it's not coming in this season.
Secondly, let's not forget that plenty of things get developed for Broadway, and even announced for a particular year, and end up coming in several years later - or as the case often is, never manage to get to Broadway at all. My philosophy is to not hold my breath. I generally don't assume anything is actually happening until we get a theatre announcement.
Obviously everybody can do as they please, but my personal recommendation from experience is to not let limbo projects like this occupy too much of your thoughts.
