No, no idea. The English language release was postponed due to the Covid-19 lockdowns in 2020, which seems odd as getting a book out there is a good idea when people often have more time to read and think. Since then, no new release date has been announced. I really hope it's not been cancelled.
For what it's worth, I bought the French version on Kindle, and managed to read it using a combination of my poor French and the built-in translate option. I could highlight 2-3 pages at a time, translate to English, and then work thru that way. It took me ages, but hey, that's what being a super fan is all about!
