According to Amazon.com, the libretto is being released in paperback in Feb. 2023 and is already available on Kindle. Not what sure which version of the libretto, but I think I remember reading that it was going to be the 1981 version. Hope so.
That libretto has been promised for years - they just keep pushing back the date. Maybe they will publish after this revival - but that often takes a couple of years.
And I don't think the Kindle version you're seeing is the same, though it's linked from the libretto pre-order page (I'm seeing it described as "Digital Sheet Music").
