Well U2 like to announce tours about 4 months before they start so a Feb/March tour of Australia means that it will be announced in October/November...
And if thats when the official announcement is we should be hearing all kind of crazy rumors and speculation! Im hoping that the Brisbane concert will be at Suncorp Stadium or the Gabba, not ANZ as last time as the transport thing didn't work at all!
Also just in case an U2 staff ever drop by... If you are worried about transport costs then put on more concerts! If AC/DC can do 2 or 3 stadiums in each city and Pink can do 10 arena shows you can do more than one too!
They go wherever the tour promoter can get a slot. For us it was AAMI Stadium, certainly the worst stadium in Australia, because it's falling to bits and the sound and viewing was absolutely crap - though Adelaide Oval would have been great, just driving straight into the city rather than having to put up with the traffic down at West Lakes because anyone that's been there for Showdown or any concert would know.
But compared to The Claw, how big is the Black Ice stage?
