Yep, they could play two times in a same city in a same tour (like Washington), making 60 concerts in a same country but cound't do just one concert in Australia, Brazil and all "rest of the world".
Australia, like South America, had many BJ fans and we deserve a concert too.
I think they didn't come just because US like they again but they oughta know that when them records didn't sell in US (like These Days, Bounce) the "rest of the world" was helped and only because us these albuns sells some millions copies at least...

Rolling Stones played in Brazil, U2 played in Brazil, Madonna is coming, Oasis is coming... they don't come just because Bon Jovi don't want to play in Brazil. They preffer that american arenas with 10,000 fans. Just it.
