I was going to buy a Switch but I'll hold out for this model. Hopefully there is a Pokemon Legends: Arceus bundle lol.

I don't get your point. You think that Nintendo will never get streaming platforms even with updated 4K HDR+ support?

Rumor mill is turning and says it could be NVIDIA ORIN chipset but that would be a huge jump in performance and TDP including DLSS2.0 support.

No. I'm telling you that thinking Nintendo is making a Switch revision with 4K output because they want to get streaming platforms is idiotic because one: Nintendo doesn't give a damn about streaming platforms and two: streaming platforms don't need 4K in order to want to support a device, like in the examples I gave to you. 

If Nintendo is making a new Switch with 4K output is simply because they plan to make use of it themselves. Not because of streaming.

I have a hard time buying that. That's Nvidia's cutting edge SoC. Nintendo tends to go with older more established hardware. Maybe for a true Switch successor but for a revision, ORIN would be far too much. I think at most they'd go with Xavier. It's Volta based so it would a Tensor Cores which are necessary for DLSS. Volta is two gens old, architecture wise, for Nvidia. Plus it would address one of the biggest developer complaints about Switch. Memory bandwith. While hardly blisteringly fast. Xavier has 5 and half times (136.5GB/s) the bandwidth of Tegra X1 (25.6GB/s).

No. If they go for all these streaming platforms it's Wii U 2.0.  Wii U had the TV App. It had Netflix, YouTube, and Hulu. Menus were slow on Wii U. Switch cut the fat. Wii U tried to be the Streaming box and the Game box.

Xavier has too high a wattage. There is a 15 watt Orin variant. Better performance for less power consumption.

Orin isn't designed for consumers products. And Ampere is relatively new to the market and would be cutting edge. Nintendo wouldn't go for that. For costs reasons.

The original Switch SOC is based on Tegra X1 T210 - 20nm (15W) and was clocked considerably lower to meet performance target and portability. Nintendo then released and updated Switch (16nm) based on Mariko which has higher clocks and improved performance.

If they used 10nm Finfet (from 12nm FF) on a Xavier based soc - which is already a product ready and can be built with Tensor cores in mind. But yeah I would say 10nm since everyone (bar Apple) wants a slice of that 7nm pie.

Ampere is not exactly known for it's power efficiency. It's actually considered the weakness of the architecture. I wonder what they couldn't get out of a 15w Ampere SoC.

Edit: @hinch I agree with you on the node size situation. Whatever Nintendo chooses, they are going to be on node that isn't in high demand. With the way the Switch sells they can't afford to have the same issues as Sony and MS. AMD isn't TSMC's first priority. Apple is, so any node Apple is on will be one Nintendo avoids.

Xavier can scale downwards to 15w and even 10w.

Due to compatibility reasons, I would personally not expect anything more than Tegra X2/Pascal.
