I'm thinking so too. Nintendo needs it released asap, and so will be putting good resources towards that.
The game is already gold and hell released in Japan now right? So only thing to do is dub and translate. Sure its a huge game and rpg so a shit ton to translate, but thats someones JOB, not just hobby. So having like a half dozen people working 8+ hours a day shoudl get this done somewhat fast.
Dubbing I don't imagine takes more than a week of a voice actors time. So its really just translating all the text, and then deciding on what everything is officially called in order to tell the dubbers what to call shit.
I would think they could have this finished by september if they started TODAY, but they have stuff already done.
