I checked with my local liquor store yesterday here in Tucson, who specializes in weird imports, and they said they've had a lot of people looking for it. I left my phone for them to call if they hear anything. The clerk and a customer both chimed in about how awesome Iron Maiden is, and one guy asked, "is it in imperial stout called Mother Russia?"
A bar around these parts that is an "Irish pub" said they will eventually be getting it in either as bottles or on tap (!!!), but I'm not gonna hold my breath on that one.
