I think it's important for Nintendo to have some way to keep up with next gen. Switch ports right now are hard but next gen will be impossible regardless of how much money switch ports make.
Also DLSS more or less runs on tensor cores added to the gpu. I don't know if enough tensor cores could be added without redesigning other components.
My 3 spec predictions.
Option 1: New Switch
Slightly upgraded CPU
Slightly upgraded GPU+tensor cores for 720p to 4k
8GB ram
Faster storage
Option 2: Switch home system with streaming
Closer to series s but focus on DLSS 2.0
Option 3: Switch HD dock
Put tensor cores+hardware in the dock and not the switch
DLSS to 4k while plugged in, regular switch when not
i mean, i don't know technology as well as you it would seem so i'll trust you on the tensor core thing. i'm okay with that,.. i'm much more of a software guy then a hardware guy. you're predictions sound reasonable i suppose. what you did that i'm not seeing in the rumors is make the "xbss" specs a home console only device. i can get behind that idea. i really don't see option 3 happening.
however,.. those don't look like small architecture changes to me. how natively BC would that be to the switch's software library? seems to me to be kind of disruptive.
but i'd be more likely to buy a home console only switch then the current version. i don't really want a switch for myself but my kid is 6.75 years old this christmas so it's been in the back of my mind he'll be getting one. he loves playing lego games on ps4 with me but we are down to only 3 more games and after lego there isn't much in the way in age appropriate content. a home console only version gives me a lot more control in when and where he plays as well as making it easier for us to play together.
sony really needs to put some more focus kid appropriate content, imo, because it is sony moreso than nintendo that will be selling me a nintendo switch..
