well of course you will have higher margins if your entire business model is revolving around buying the cheapest tech from Nvidia and ripping off your fanbase with "never discounted" games all this while doing your bare minimum at providing any advancement to gaming industry! Voice chat? What is that! VR? Nah.. any GPU tech? Nah... Upscalers? Nooo...SSD?...nah.
Shhh .. just buy whatever outdated tech in our industry , sell it .. profit!
While looking at Sony, they have always been at the cutting edge trying their best to forward the industry and the examples are plenty with the latest PSSR tech that rivals Nvidias best efforts, PS4 cache scrubbers and ALU config that was carried over to AMD roadmap, PS5 SSD that even predated the speeds of the standard PCI, VR ventures ...they are trying to advance the industry all while having really advance infrastructure for online and cloud streaming.
Of course margins will never be the same! And this luxury for Nintendo won't last once Portable PC gain more traction and the big boys arrive!
Yes I will double down on my original point, Nintendo will never have their luxurious handlheld market for them, now how about sharing the numbers of the "console space" that they competed directly with Sony in? Numbers wont be pretty at all.
So yes, they are So PTSDed to the point that they just recently mentioned that they want nothing with "competition"
So even Mayamoto doesn't agree with your conclusion
