always this "what will be the gimmick" discussion...
switch is the ideal system for nintendo currently, no new gimicks are possible (back then all of then had rather new or unused tech, now everxthing is full with sensors and touch screen and stuff. adding some exotic sensors? really to far out. adding VR? the closest to "new gaming posibilities", but i dont belive it.
Experimentation is still possible (just add any sensor in any form factor you want, the joy con can communicate with them (see: ringfit).
The most out there thing would be... adding cameras, and they had that with the dsi/3ds/wii u.
You can add gimmicks in post to the console, why push them from the get go and risk another wii u (high cost for the pad, that kinda was unused for mot games)
It's bound to happen. Nintendo isn't in the power arms race. Portability set them apart, but I feel like they may venture even further to differentiate them from the market. However, Furukawa is super conservative, so who knows.
they are not.. but this case is different.
wii -> wii u they tried to advertise with graphics... but it was so close to the other releases that it was a really bad timing.
Switch 2 will be shockingly close to the big ones while being portable, since it will need just a fraction to render games at 720p instead of 4k.
it will be worse...but not to a degree prior Generations where.
And even better: its a huge jump from their current power base, thats roughly the same since 2012.
In other words: the first power jump where it does not feel like stalling since the GC.
GC-> Wii no hd, only double GC power
Wii -> Wii U way more power... but closer to last gen then the one that came just a year after it
Wii U -> Switch move to portable made a huge jump impossible, sizable jump, but still not worlds.
