I’ve heard of ride closure stories in the past where the staff have literally turned up the next day to see the ride locked up without any prior announcement, so I don’t think ride ops would necessarily know about the closure of a ride at the park (even if it was their ride) prior to the closure happening or being announced publicly.
Apocalypse could be staying, but I know at very least that at some point, it was intended to be going. Attraction Source was quite literally told by park management at a media event for Vikings that the ride was leaving at the end of 2022, so even if it’s no longer on the chopping block, it certainly was earlier this year. I should add that like others have said, the ride has been seen listed on multiple different ride sale sites in the last year, and it’s still listed on some.
Given that only one tower is presently operating and the others looked as though they hadn’t operated in quite some time when I went in June, I would not be one bit surprised if the ride did get removed at the end of the season. Things could admittedly change, but to me, the ride looked like it was holding on until the end of the season in anticipation of either removal or a very big refurbishment based on how only one tower was operating and the others looked well and truly SBNO rather than just “temporarily closed”.
