It seems some misinterpretations are floating around regarding the next Switch model. Since I was asked to clarify, here's what we know so far about it:
1) A new retail model is definitely being worked on for release. There have been references to it since firmware 10.0.0; 2) The next model's codename is "Aula" (for comparison, the Lite model is called "Hoag") and its form factor is codenamed nx-abcd (for comparison, the Lite is nx-abcc);

Now that the first Mariko based Switch has finally been announced, I believe it's a good time to provide some insight on what has been going on inside the Switch's HOS regarding new hardware. I've talked about it before and I've been adding RE'd information to the switchbrew wiki for quite some time. Some folks actually noticed and were able to connect the dots as seen in a recent @digitalfoundry video, but there's quite a bit more to this story.

It seems my tweets from yesterday confused some people. I don't blame you. Me failing at basic english ("until" instead of "while", smh) *and* posting the wrong hash didn't help at all, but what can I say? I was too excited and tired to even notice. :P I'll now try to provide a brief overview for all this.
TSEC is a controller used in most Tegra devices, including the Switch. Like many other controllers found in Tegra devices, it is powered by a Falcon microprocessor, but with additional crypto capabilities (via the SCP).
