In a recent interview, Shin’en revealed they are working on a new project and it will be on a Nintendo console. However they also noted that it is too early to discuss the finer details
The problem is I can’t talk about it. I’d really like to talk about it, but if I say anything…. let me put it this way: we’re very happy to work with Nintendo, we’ll keep doing it and our next project will be with them. We’re also carrying out new experiments and creating new prototypes, but I can’t talk about this either, because they’re so deep in their initial stage that there would be no point talking about it now.
