While I have no contribution to whether or not this is true or false, I hope it is true, and that Iron Maiden comes back to play at least a FEW US cities in the next leg.
It doesn't have to be such an extended tour like this past summer, and I understand the complaint "Let the rest of the world have their turn!", but maybe hit up just the BIG cities (maybe a few along each coast, and then like Chicago in the middle, etc). I would love this because, obviously, it would mean I'd get to see them yet again. And it would make sense, since this Maiden England tour has arguably been their most well-received US tour in many years.
If this happens to be false, I am at least hoping still for their possible one or two Florida concerts. I would plan a trip/vacation down there in correlation of when Iron Maiden would be there.
