I can't find this mentioned anywhere else on the forum, but BD Addik are advertising a new colourised version of the original black and white The Blue Lotus for 8th January 2025. French language, but Cigars Of The Pharaoh wasn't too long in coming out in English too. I can't find it listed anywhere else, but BD Addik is reliable as far as I'm aware.
Le Lotus Bleu at BBAddikThey're also advertising a new series of Phillippe Goddin books, again in French, the first of which came out in October, with the next due in December. (These are advertised elsewhere, such as Amazon and Tintin.com, which lists projected publication dates for the entire series over the next four years). The series is called Les coulisses d'une œuvre (Behind the scenes of a body of work), and there's one planned for each Tintin book. It's hard to tell whether these are entirely new works or recycle previously published material. The first two are certainly shorter in terms of page count than Goddin's previous monographs on the same books.
