That sounds correct. Albums normally released on Monday in Europe (5th), Tuesday in USA/Canada (6th) and the usual release day the week before in Japan. The 31st is a Wednesday. The date I have given on the ABB pages for Japan:
i heard no bonus track on this one. I also ordered the bigger bang release for august 16th. hope i get it, and dont have to wait until the september to hear this sucker.
They have bonus cuts - didnt get the Japanese No Security (which had one) but "Bridges to Babylon" had a live '95 Angie (sturdy artwork w/ slipcase too), tho I wouldn't expect studio outtakes.
Usenet: I´m talking about newsgroups. There are many newsgroups where new albums are posted often even before an official release, one popular group is only about Stones. I think A Bigger Bang will be posted there at the end of August. You need an account to read newsgroups.
