I used to think so, but Im not really sure anymore. Theres a lot of support from third parties who bring new IPs to their system now and Nintendo are great at coming up with new experiences in their already established IPs. Theyre characters are so iconic at this point and they dont seem to become less loved as time goes on. Sure it would be nice to see something new, but I personally cant even remember the last new IP from them I cared about. Maybe Pikmin?
