According to this interview, that could be the case.
"Koizumi: Well, this is my personal opinion but I think that with all the experience accumulated by the teams of Mario or Zelda, it would be difficult to fully leave a key episode of the series to external studios. However, as we have found ways to collaborate on projects with other companies, it would probably be possible to do the same thing with Mario finding a truly talented and motivated team. |
Just stating that they're working on a new project, nothing here to suggest open world Mario really.
