I find it seriously annoying that Australia gets the games last. When BW came out in America a few days before Australia, my cousin was mocking me on Skype about it...
Yeah, me being an Australian myself... I know how you feel. There was a time where Australians got a main game before America and that was Gold & Silver.
In this case, they might do the European and Australian releases simultaneously with the US. I'd be kinda surprised if they did one day separating all three regions' release dates.
