I doubt it. History part 2 documentary was a great disappointment, personally. There was no new material. They've compiled SiT era from sources that were already available to us. Someone even did a bootleg compilation of all available SiT era footage, I was a bit down because I expected to see maybe a new interview there, but alas I've seen it all. Imagine the disappointment when History 2 featured only a subset of of the stuff from bootlegs...
If they had sub-par whole shows like "Beast on the road" it would be released on history DVDs. If they had a track or two of "unsurfaced" bootlegs it would be inserted somewhere in the documentary, as a transition video or background music. No, unfortunately I don't think that stuff exists. Same with every tour until DoD or such when they started recording every show.
Buenos Aires gig from 1998 was destined to be a VHS/DVD. Someone got a hold of master tapes and the analog copy of an analog copy got released as a pro bootleg, with severely degraded AV quality. If you had things like this from NPFTD era, then maybe. Cause its indicative that Maiden may have a original master somewhere. Simply put, recording a show, the oldschool analog way, was only done if you really intend to make a money off releasing it. So whole shows? Doubt it. Bits and bobs, maybe. However I'm also vary of any TV-sourced material being revealed, Maiden has been too big of a band for a long, long time, recordings would surface.
I've been in the bootleg circles enough to notice when in mid 2000s new Maiden boots stopped surfacing. Since then releases have been following the ongoing tours, and only 2 or 3 new audience boots of long past tours surfacing ever since. So I keep my wishes accordingly, pro Ed Hunter tour stuff and AMOLAD tour stuff.
And To Tame A Land. C'mon you have to have pro audio that can be remastered in the vault. Actually that's one of my realistic hopes too, that Maiden has a lot of soundboard feed tapes from the 1980s that'll get released in near future.
