Zelda: Triforce Heroes and Animal Crossing: Amiibo Party Co-Development Confirmation?
It seems this may become the official development process for most internal games now at Nintendo EPD (and across).
The Legend of Zelda: Triforce Heroes (co-developed with Grezzo)
Animal Crossing: Amiibo Festival (co-developed with NDCube)
Star Fox Zero (co-developed with Platinum Games)
There are definite Nintendo EPD core teams in the forefront and their engines and assets are also involved, but it seems that none were granted a full development staff. Obviously Nintendo is trying to internally commandeer a lot more games, so they have to be smart about filling out their production teams
