Hi! Sorry, I managed to lock myself out of my account for 24hrs, could log in, but not post (which Sicy has kindly fixed). It was funny watching you all go into a panic over that time. The floodgates are open now, and that Melbourne article should be all the semi-formal acknowledgement you need to feel 110% secure that it is happening, and I'd expect the whole formal announcement today or tonight depending on whether it's coming from Oz or Ireland/US.
On Sydney, put it this way, I haven't heard that it's not 4 x SuperDome. With Auckland and Melbourne probably using the stadium setup, that might have changed, but I haven't heard anything to suggest that. It is actually possible that they may be able to squeeze the stadium set up into the SuperDome as well. Remember they fit Popmart into Burswood. The SuperDome is larger than Burswood in sheer size (and the SuperDome is larger than most of the US arenas they've played in), but Burswood had the ability to majorly adjust it's seating configuration to create the room. The SuperDome can do this somewhat (much of the first section of seating is completely removeable) but maybe not to the same degree. I can't see them going to the effort of bringing both stage setups down here, so maybe we'll see a third hybrid set up, see Brisbane and Sydney go to stadiums, or get, in my opinion, the ultimate set up out of all the U2 shows on this entire tour anywhere in the world - the stadium show, in an arena (FUCK YES!!!).
Anyway, we'll know it all very, very soon.
