The title of the thread is "Future History Tours" so I'm pretty sure it's fair comment to ask why people are talking about post-2000 tracks; unless of course you consider post-2000 tracks candidates for any (likely) "history" tour(s). I'm just saying I do not (at present), as this makes the distinction, between said "history" tours & plain old normal tours, literally non-existent. Unless your saying "it's 2020 --what tracks do you think should be considered for a history tour?".
Talking about the 90's (at least the early 90's) seems fair enough (even right now), as chronologically this is the next period a history tour would cover --& this is quite far, now, in the past. But post-2000, to me, seems very recent. BNW will creep into my thoughts soon I suppose, but that's it. Even hypothetically, I don't see Maiden being around long enough (as you state) for DoD, AMoLaD, & TFF to really be candidate albums for any history tour(s). I accept they are, now, in the past. But history implies, to me, something a little more removed.
