Tai Yasue the co-director of kingdom hearts 2.5 HD and kingdom heart III explained while an interview with IGN, Square Enix plans to release HD 1.5 Remix and HD 2.5 Remix to help the latecomers of the franchise.
"When we first came up with the idea for Kingdom Hearts III, it was always 1.5, then 2.5 and we were always thinking about those three titles at the same time," he stated. "I think [putting the games on PS4] is something we’ll explore. We understand what our players want, so we will explore the possibility. I’m not making any announcements though, we can’t make any announcements yet!"
Yasue was hesitant when asked whether the first two HD remix 1.5 and 2.5 would be coming to the Xbox One, this was initially thought to e and exclusive deal with Sony it would seem that the resource plays a big part as well Yasue he said. "It’s a big old question. There’s a lot of things we need to think of when we consider consoles. One of them is what our players want, so we will definitely consider that. But there’s also schedule constraints, as we really don’t want the development of Kingdom Hearts III going later, so we have that to think about. We’ll consider all these things and come to a decision."
