I agree one hundred percent. Nintendo always like to add unique features to its new consoles, but I do not see them moving on from the hybrid concept anytime soon. With Switch Nintendo has been able to hold onto their dominance in the portable market with no real competition now that Sony vacated that segment of the market. When Nintendo decided to try something completely new with the Wii, this was after three consecutive console generations selling less and less. Sony was so dominant during the PS2 era and with the additional competition from Microsoft, it made sense to try something completely different. We have seen Nintendo make incremental changes without starting from scratch. The GameBoy to the Gameboy Color was a very modest change, and then the GB Color to the GB Advance was pretty straight forward. DS to 3DS, additional features certainly, but didn't reinvent the wheel either.
Switch getting out of the gate with a strong start wasnt just because the hardware itself struck a chord with consumers, but also because the roll out of strong first party titles was consistent for the first year. This will be very important for the Switch 2. Having a new Mario Kart, 3D Mario, Zelda and Smash Bros in the first 12 months was critical. Not saying that it has to be that exact same lineup, but there needs to be a strong first year offering of Nintendos heavy hitters.
