Nintendo games have been (basically) at the same level of graphical power since 2012 and Luigi's Mansion 3 is one of the best looking games last gen, teraflops be damned. This will be a generational leap in technology for Nintendo by every conceivable metric and the real-world performance that results in games that "should" look better than any Nintendo game has ever looked and by a fair margin . Couple that with competent ports of current gen 3rd party games (Call of Duty we know is a lock, and Elden Ring and whatever else) and the plethora of indie titles and they look to be in very good shape. One thing those other handhelds don't have, as corny as it sounds is Mario. Graphical power hasn't sold a damn thing for Nintendo since Nintendo 64.
The measurables don't matter outside of making quality content that doesn't play like dogshit. I can barely tell the difference between PS4-Pro-PS5 games now. I don't think I am an elitest player anymore despite owning every console save for the PS5pro and an ok gaming monitor. Diminishing Returns in gaming are real.
But one problem remains.
Lets just say most people here own another console next to switch. Why wouldnt you.
But they still play 3rd party games on other systems not just for performance reason but also social aspect of it .
And those third party games are either on gamepass or on sale down the line , like few months in.
On nintendo you dont see those type of discounts.
I guess what i am getting at is , i believe there will be some support at the beginning for third party but later it will be very selective.
As is the case for the last 10 plus years.
So even if it would as powerful as a ps5, third party sales on it would be still very low.
