considering Falcom doesn't even allow work to start on localization until the game is complete, I don't see this coming stateside "not too long" after release. It's also why we're so behind with Trails. I mean at this point we're a whole 2 games back with Kuro no Kiseki 2 [I believe] having released almost a year ago in JP.
That being said, I can only hope that if NISA is the publisher for NA that they have time set aside in their schedule to get YsX localized and out the door w/in a year. The good news for Ys is at least there isn't a backlog of games already.
Hopefully they release the NA version not too long after or at least offer an English dub version for Asia at launch and I would end up buying both.
Love these ys games. Pretty damn good
