Probably depends on Nintendo's success in the future.
What's weird is that, so far, the franchise's 3DS releases haven't come to the west at all and, to my knowledge, haven't been announced for a release outside of Japan so far. Same goes for DQX, even though that's on 3(!) different platforms already in Japan. That definitely is a bad sign either for DQ in the west, or at least on Nintendo consoles over here.
I'd definitely appreciate it if that meant the franchise would move to the PS4 (and Xbox One I guess) because, even though I'm not a huge fan, I'm trying to get into the franchise anyway and the visual style, and anime-style cel-shaded games in general, would be much more appealing to me than any realistic art style. A good-looking, anime style game with decent gameplay and story could definitely be a system-seller for me.
