Told by a few Asian importers they got their stock for Japanese BladeStorm (supposed to be released on 8/30) already and will be shipping them asap. Large websites like Play-asia and Yesasia probably will start shipping either tomorrow or the day after.

One interesting factor is that even though it is the Japanese version, you can select English as the language. It does not translate the menu for players, but now all voices can be heard in English, which means the localization will be much faster for US release. (very wise decision) If anyone is interested in this game, certainly a good news for importing.
