"Mid" Summer has certainly past, but as Tomas did say "Mid to Late Summer" — and "Late Summer" can reasonably be expected to last at least all of August through — there is little reason to fret as of yet.
I'd surmise that the reason for UO not being mentioned in the plans for upcoming releases is simply that it's so far down the pipeline now that Ligan internally to all practical intents and purposes already consider it released. It's no longer "upcoming".
Apart from one or two small lapses, Ligan are proving remarkably resilient to the SJWs and other Culture War activists, firmly standing up for their creative and ethical integrity in the face of Cancel Culture. I can't see them delaying a book because there are a few people lurking about desperately looking for an excuse to scream about being offended on somebody else's behalf because — gasp! — someone dared mention the War (or whatev)...
From all I hear, the people actually living through it would prefer the rest of the world educated itself on what it means — an effort towards which a publication like UO ought to contribute — rather than tried to hush it down, which only helps the Russians.
Don't fret. UO will be here soon.
