Eiji Anouma recently revealed in an interview that Nintendo has asked him to make a new IP. At the same time, he says Nintendo wants him to continues on the Zelda series. While he wasn’t able to say much about what this hypothetical new IP would be, he did mention liking the idea of a game where you are living as a thief
“Actually, Nintendo has been telling me to create a new IP. But then, they’re also telling me to make more Zelda games. I can’t really share much; I’m not sure I’m allowed to say anything. But I really like the idea of a game where I can live as a thief. That’s all I’ll say.”
Whether this is a hint to Anouma’s new IP or not, or if a new IP is even in the works, remains to be seen. However, it is good that Nintendo is looking to make new IPs and new content
