I think if Maiden does it they'll be upfront from the get go and say it'd be the last major tour and there'll only be mini-runs of 8-10 shows a year afterwards or that they'll continue as a recording band.My thoughts as well. I doubt they will market a "farewell tour." As a side note so glad I never fell for the shit that Kiss pulls. As far as I'm concerned their farewell was when I last saw them in 2000 with Peter and Ace.
Kiss on their latest tour started off saying "That's it, there's nothing coming after this. It's over." Now they're being wishy washy as to what's actually coming next.
