There's plenty of good English dubs out there. I think this game is very likely to have an English dub too. Though not every game lets you choose languages and some can be English dub voices only with Japanese games in the English version.
But of course like i've mentioned before, I listen to both English voices in these games as well as the Japanese voices since I usually enjoy both.
What concerns me though is that if it's going to have an English dub like the Studio Ghibli movies where it mostly uses like famous movie stars doing the voiceovers, or would it be more like ones we can recognize from other Japanese-created games and Anime series.
