Honestly, Nintendo's probably our only shot but I wouldn't put too much hope in that either. This remake looks worse than the original in some ways, I think a global minded remake would've ended up a lot different.
I have no idea why they went out of their way and trying to reproduce the same game in a chibi artstyle when they already had all the models ready from the online version; as far as I know, the game ran on a 3ds through cloud and on a Wii, so definitely it's not for a technical reason.
Nowadays we have all kind of artstyle, this game pales in comparison to either DQXI (obviously) and the upcoming 2D-HD remake of DQIII, from a marketing pov it definitely doesn't look promising and we already talking about DQ which is not a million seller in the west (and Square is known for having unrealistic expectations about their games, so there's that also).
That being said, I still want it, I doubt the cost of localization is that high and the game would still benefit from the notoriety DQXI got anyway
