This Video goes over Nintendo own franchises that still have not yet had a new game on the Nintendo Switch as of June 2024. Franchises include Wario, Warioland, Chibi Robo, Star fox and Donkey Kong.
I think this generation overall has been a weird one for the industry. Nintendo has been better than Microsoft and Sony as far as releases, but I would agree it feels like many of their own IPs only have ports to show for. Some successors have been less than ideal too, I’m looking at you Switch Sports. At this point I’d expect anything from these series to be released as a dual launch for the new switch successor if not just released for the new system alone.
