Kingdom Hearts 3 director Tetsuya Nomura has suggested that the game could come to the Nintendo Switch. However, its production would only start after the Xbox One and Playstation 4 versions of the game are complete.
Whilst speaking with IGN at the 2017 D23 Expo, Nomura had this to say:
The Nintendo Switch is definitely a very interesting piece of hardware, but if we lightly say, ‘Oh yeah, we’ll be on the Nintendo Switch,’ I’m sure people will come back and say, ‘But what about the PS4 and Xbox One? We want them out first. Don’t focus on other platforms. So for now, we want to focus on what platforms we’ve already announced we’re going to be releasing Kingdom Hearts 3 on. And so after, perhaps, maybe we can start thinking about other possibilities.
Further to this, Nomura didn’t entirely discount the possibility that the recent Kingdom Hearts remaster collections could become available on other platforms after Kingdom Hearts 3 has hit the market. For now, the studio is focused on releasing games on platforms that they have already announced.
