Please bring this to North America soon after it is out in Japan, Nintendo. Just translate it into English and then put that version in the e-shop for both N.A. and Europe. No need to redo any of the voice work. Just translate the text, add any needed subtitles, and then call it a day. And why you're at it, maybe you can do the same for Rocket Slime 3 since that title would probably take only 2-3 days to translate.
If Nintendo doesn't publish DQ 7 and later Dragon Quest X for Square-Enix, I'm worried that we'll never see them. Square-Enix doesn't seem to care about their North American Dragon Quest Fans anymore.
