Source is game watch, article from gematsu. Sounds like there is potential for an overseas release but I wouldn't read too much into it tbh.
The staff were also asked about English voice acting and multiplayer features.

Game Watch quizzed Square Enix on the potential of an overseas release of Dragon Quest Heroes during an interview at the Taipei Game Show.
I want to proceed thinking positively, Square Enixs Ryutaro Ichimura said in response to the question of a western release. Since we were able to announce the Chinese version in Taiwan today, seeing that reaction, I want to spread it even further around the world.
The staff were also asked about English voice acting and multiplayer features.
Game Watch asked if a potential English version would include the option to switch between English and Japanese voice-overs.
We havent decided anything about that yet, but if itd be better to put it in, thats something well consider moving forward, Ichimura said.
Koei Tecmo producer Kenichi Ogasawara added, If such a need is strong, were going to consider it.
Finally, the website asked about multiplayer. Specifically, whether or not it exists within Dragon Quest Heroes.
There are no plans for completely synchronous multiplayer, Ogasawara said, but we will be incorporating a fun little element that uses the network. We havent officially announced that yet, but I think youll enjoy it.
