I'm more than fine with Maiden ending (?) in 2026. I remember a couple of interviews when AMOLAD came out, bringing up the issue of retirement. Steve said something along the line of "we treasure every show, because we know this will not be forever, we're not young and Nicko is whatever years old doing a physical set", and "I have always said that Maiden will do 14 studio albums". Mind you, I was 16 at the time and immediately changed my MSN screen name into something dramatic about how I was deeply saddened, mortified and whatever about the fact that Maiden had done their final album.
So essentially, I had less than two years as a Maiden fan without the spectre of retirement in full view. It has been coming for a long time and if they call it quits tomorrow, with no more tours and nothing else than more Maiden Beer, I don't think I would sulk, I would just be thankful for about 15-17 more years than I thought I was getting when I was 16.
