According to a rumour GameXplain uploaded a video about it's apparently Scalebound.
Scalebound was originally a Wii game so I suppose it not completely impossible if Platinum went back to the original concept of Scalebound they had visioned, and restarted development under a different name. In another partnership with Nintendo of course.
Still I feel like it's unlikely.
