Just got back last week. Started off as a sold out trip, few backed out, another was picked up. Should have been 13 of 16 bunks filled. Airline issues left 2 people without flights in time. So we were 11 of 16 bunks. Be sure to have your trip insurance for this one.
What we heard was the same as the OP. 2026 is the last year.
I don't think this is the end, forever. I think there will be an occasional trip/season. How that happens, don't know? Not only is it for those with disposable income, roughly 2X the cost of Truk, it is for those who have time. My trip needed 3 weeks off work. It was almost a week just to get there. Travel is 2 days to get to Kwaj, 2 days on Ebeye (those that tried to skip this step missed the trip, and some of the delayed luggage actually arrived during this waiting period). A day diving in Kwaj, a day of motoring to Bikini. Now you are diving in Bikini. That's a lot of time not spent diving in Bikini. I really wish the land operation stayed alive.
