British heavy metal legends IRON MAIDEN have posted another graphic on their official web site (see below) — featuring the Union Jack flag as a backdrop — prompting speculation that they will reveal U.K. dates as part of their "Final Frontier World Tour". The official announcement will be made at 11:00 a.m. GMT on Thursday, November 11.Last Tuesday (November 2), IRON MAIDEN confirmed that it will once again be boarding Ed Force One in February 2011 to fly 50,000 miles round the globe on its continuing mammoth "Final Frontier World Tour", playing 29 shows and visiting 26 cities in thirteen countries across five continents, with the band's lead singer, Bruce Dickinson, again in the pilot's seat. Since its release in August on EMI (UME in the US), "The Final Frontier" — the band's 15th studio album — has proved their most successful chart album to date, registering the No. 1 sales chart slot in 28 countries around the globe; from Lebanon, Arabia and India in the East, to Canada in the West, New Zealand down South, throughout Europe and across Latin America, as well as reaching No.1 in Billboard's European, Tastemaker and Rock charts, and No. 4 in the USA, which is the band's highest position ever there. Having already played an extensive 25 date North American Tour and some selected European shows this year, MAIDEN will undertake a full European tour in the summer of 2011.
