It's likely, considering the localization is shorter than usual it may well be the 12th and I'm hoping for it too. Although I'm not from there it would be nice to see you guys getting it the same time as others.
I think that the leaked date will be likely true.
Keep in mind these will be the first games since FireRed & LeafGreen to have the Japanese and international releases in the same year.
The translation team sure have been working hard just to get the game released internationally this year rather than waiting until 2013. Most international releases usually occur like, one year after the Japanese release.
