They have expansions planned far in the future. They just didn’t anticipate the demand. They announced yesterday that they will reprint the First Chapter and launch the reprint alongside the first expansion (Floodborn) in a bundle this holiday 2023 (USA) and do the same for Europe in January 2024. They will be also launching Floodborn expansion as a solo expansion beginning in mid November in LGS and Dec 1st in big box.
I was able to get the 3 starters and a trove (8 booster packs) just last week when my local big box did a big restock. I’ve played the game with my wife mainly and we are both loving it. I don’t think it’s on life support, I think it just had a rocky launch.
