Hate to be a downer but realistically there is a better chance for it to be released digitally on the eShop than retail, so you should try for that. Dark Souls PC is a completely different ball game.
Also it's not really that bad if NA doesn't get it, you'd rather the fans/newcomers got a good One Piece game on the 3DS right? It's still in English, so you could always get a European 3ds if you are desperate, or just wait it out.
