Memo Aponte Mille, the voice actor for Hiro Hamada in the Spanish dub of Big Hero 6, had recently published a video on his Instagram teasing his involvement in dubbing a role for an upcoming new game along with co-star Alan Prieto, who voiced Baymax. The video seems not to be on Instagram anymore, but KHInsider reports that it was published on March 7, 2018. In the video, the actors say that they can't say what the game is about - so we cannot confirm if they are talking about Kingdom Hearts III - but hope that we will hear about it soon.
You can watch the video below.
There are still no concrete news about the voice acting for Kingdom Hearts III apart from the Japanese dub, which can be heard throughout all the trailers released since
While the newer Kingdom Hearts games did not receive dubs in languages other than Japanese and English, both Kingdom Hearts and Kingdom Hearts II - the main games in the series so far - included Spanish, French, and German dubs. Last year, we helped our friends at Disney Central collect signatures for a petition to Square Enix requesting that these European dubs return for the long awaited Kingdom Hearts III.
While this news does not confirm that there will be Spanish (or French or German) voice acting in Kingdom Hearts III, we can only hope that there is a full localization in these languages to enable a wider fanbase to enjoy the last instalment of the Xehanort saga.
