Usually the ISOs are already on the server days before they go live and nothing was seen when we scanned for ISOs today, we'll have to wait. Considering 26x00.5074 is causing all kind of software/games to stop working could be a reason for them to halt the release.
25H2 in general is not very stable as of lately. Lots of slow downs and UI freezes, at least in the Dev Channel (where this is to be expected). 26200.5074 also has these weird UI freezes and glitches. Seems like the update is far from being done/complete yet.
Canary, in contrast, is exceptionally stable. Despite being based on an entirely different platform (bromine).
How many 25H2 releases do we now have? You keep telling the same over and over and over and over again, just the one 25H2 RP channel EP and a very buggy 24H2 retail channel 26100.5074 LCU.
The 25H2 preview ISO that was scheduled for this week was going to be 26200.4946, but it has been delayed until next week or the week after.
Installing the 25H2 EP on 26100.4946 did not bump to 26200.4946, why would msft release a 26100.4946 ISO and next a 26200.4946? And not expecting a 26200.5074 ISO either, but as said before all can happen, we'll see when they release the ISO.
I don't have all the answers, but I do know that the 25H2 iso was going to be 26200.4946, and I have not yet heard that this is going to change, so I still expect this to be the case despite the delay. If that won't be the case, then that means they'll wait for next patch tuesday's build (+ image creation validation would mean that it'll be probably in around 2 weeks then), I don't know. My money's on the first option.
