Multi-platform can always provide more revenue. Nintendo could release games solely from their older consoles and still make bank. At the same time, they could also make Switch 2 on par with Steam Deck, so that almost every third-party game could still be ported to it. Those would be the optimal moves to make, anyway, which is why I'm pretty sure Nintendo will do the opposite lmao.
Actually makes me wonder....
If Nintendo has sold 132 million Switches, and they're getting 30% of third party game revenue from, let's assume, an avarage of four games retailing at $60 each, that's 2.376 billion from licensing.
Now, let's assume Nintendo themselves release 3 games a year on average for 7 years (the length of a generation) on PC, and 30% of that revenue goes to Steam. We'll assume an average of 2 million in sales per game, since some games will be more popular than others. Retailing at $60 each, and assuming Nintnedo doesn't participate in sales very often, but accounting for games that will be $70, we'll just assume $60 for the average cost, accomodating for the overall sales of their games. This is $42 they earn in revenue from Steam sales per game, time 2 million, time 21.... That's 1.764 billion.
Next, let's assume tghey make around 5 million sales on average per game that releases on their own console, which the average price being $60. 60 x 21 x 5 million.... that's 6.3 billion.
Now we'll assume that the PC market takes a share of 20% of sales away from the console market (because some people will adopt the mindset of "it's coming to PC eventually anyway"), which means we multiply the revenue from licensing and first part console sales by 0.8.... that brings licensed revenue down to 1.9 billion, and first party game sales on first party hardware down to 5.04 billion.
Finally, we'll compare the numbers and do some math....

Total (theoretical) Nintendo-only revenue = 8.676 billion
Total (theoretical) Nintendo + PC (current Sony strategy) revenue = 8.704 billion
These are obviously based on some arbitrary numbers though. They also don't take Nintendo accessories and raw console revenue into account (which Nintendo is definitely profiting by now). Each metric could be drastically different depending on market trends, and there could be other figures and variables that I failed to consider.
