The information on the HEG001 which is the commercial model of the Switch Oled was fully available after January 10, 2022, but currently is not, so I speculate that a revision of the Switch Oled was submitted for approval to the FCC which is the licensing body for technology products that are acts to be marketed.
in "Ask the Developer Vol. 2, Nintendo Switch - OLED Model-Part 4":
Yamashita: Having said that, we will have more ideas where we think "this will get even better if we can do this!" with regards to Nintendo Switch - OLED Model as well, so we won't stop carrying out these investigations going forward.
Shiota: We believe that we have to be united with the software development to create new entertainment experiences. We often say "integrated hardware and software approach".
As Yamashita said they still hope to improve the Switch Oled, it is clear that a decisive factor for the hybrid console model is the battery life, so this limits the processor, I know that many of you expect 4k games, but the main challenge to meet perhaps for Nintendo engineers is to allow using anti-aliasing technologies in handheld mode continuously, to improve games like XC2 and XCDE. In the absence of chips or by strategy perhaps the expected Switch "PRO/2" will be just a cloud service, there are official data on this (Nintendo would opt for a hybrid processing system accompanied by a new control):
As Shiota says they are mainly looking for ways to innovate in entertainment, that's Nintendo's philosophy, and we already have panteted products linking hardware and software.
And don't be surprised that Nintendo's biggest mystery is how they are going to empower Switch to have a longer life time than usual, and along with this mystery looms a game of the saga that has usually the biggest budget, yes I'm talking about Zelda and the expected sequel to Botw, with patents # WO2022130596 (Stick haptic) and Patent # 11,285,394 (Stick sword control/an improved version of the one seen in SSHD with more options).
Patent # 11,285,394 was amended to include immersive haptic sticks:
"The above processes can be applied also when using an analog-input-type direction input device that realizes a predetermined neutral position when there is no input. For example, the above processes can be applied to a slide pad, a pressure-sensitive-type stick, or the like. Further, the above processes can also be applied to, for example, a virtual joy stick formed on a touch panel, in addition to the direction input device."
It also includes this from the outset:
"For example, in an information processing system including a terminal-side apparatus and a server-side apparatus communicable with the terminal-side apparatus via a network, some of the series of processes may be executed by the server-side apparatus. Further, in an information processing system including a terminal-side apparatus and a server-side apparatus communicable with the terminal-side apparatus via a network, major processes among the series of processes may be executed by the server-side apparatus, and some of the processes may be executed in the terminal-side apparatus. Further, in the above information processing system, the system on the server side may be implemented by a plurality of information processing apparatuses, and processes that should be executed on the server side may be shared and executed by a plurality of information processing apparatuses. Further, a configuration of a so-called cloud gaming may be adopted. For example, a configuration may be adopted in which: the main body apparatus sends operation data indicating operations performed by the user to a predetermined server; various game processes are executed in the server; and the execution result is streaming-distributed as a moving image/sound to the main body apparatus ."
The adoption of a hybrid compute system (Soc + Cloud gaming), would serve the BOTW sequel well to run the game at 60 fps, necessary for a moving sword game, and perhaps scale to 4k, among other things.
The question would be if Nintendo would make the sequel to BOTW exclusive for the new controller, as Nintendo already has products like LABO, RING FIT, Mario Kark Live, which use new hardware, and games not compatible with the lite.
Also this way they protect themselves against simulation on other platforms of this IP, so important for them.
Even if they update the chip as most expect, it could be a silent update like T210 and T214.
Think of the Switch family as a game library like Android or IOS, that's why I dare to think that whatever the next Nintendo product will bring the same logo even if it is different in some aspects. In any case it seems that the sequel to BOTW will be the one who will give birth to Nintendo's hardware plans. Finally there was not only an increase in raw material for this fiscal year, but also in advertising, will Nintendo be very aggressive with some or some sales campaign before March 31, 2023.
