The official Japanese box art for Kingdom Hearts HD 1.5 ReMIX has been revealed, and one voice actor has hinted that Western localization is already underway.
Localization of the HD collection is still yet to be announced, however voice actor Jesse McCartney–who voices Roxas in the English-speaking version of the series–posted an image on Instagram (which has since been removed), showing him in a recording booth with a Kingdom Hearts game playing.
“For all you Kingdom Hearts fans. Recording the next chapter,” he said.
Now unless some secret Kingdom Hearts 3 work is going on then this must be Kingdom Hearts HD as no other games have been announced in the series.
