I'm from Brazil (region 4), so as soon as the DVDs are released I'll try to find out what the differences are. I know that the menus will be on other languages, there will be subitltes in spanish and portuguese, closed captions on the country's language, and the brazillian version is most likely to feature a dubbing in portuguese as well. Apart from that, it seems to be identical. I'm not sure about other countries, but in Brazil the pan-scan version will not be released.
