As far as I know there is no known release date for other regions than 2.
I’m in the same boat with another series that has only been released (properly
) in the US.
I ordered it despite I don’t have a region 1 dvd player.
I’ve heard that most dvd players can be made region free quite easy but it’s still a bit of a gamble.
If that doesn't work there are always region free dvd players on the market.
