Aloha !
The reason why it now seems more likely that they'll be touring different regions is that whatever the current is in the country they're doing a show at, it most likely will be more worth than the dollar. If they tour many countries in Europe they bring back more Euro's for which they get a lot more dollars as opposed to the dollars they're getting for a sold out American show.
For example; 10.000 tickets in Europe are 15.000 tickets in America.
So the money now is made outside of America which is why the rumours of them doing a part of Eastern Europe and maybe even a few more cities in Asia show up. Doing Australia had nothing to do with them being loyal to Australia but had a lot more to do with the fact that it was now financially a lot more attractive. The same goes for the Scandinavian shows last tour.
I am a bit surprised that no rumours of the shows in Germany have showed up though. Normally we know half of the tour unofficially before it's anounced.
