It's a bit shame that there is no chip part information. I am particularly wondering which microcontroller they use for the remote controllers. I will wait for iFixit's teardown review.
In general I find Fictiv is a really poor source of information. They seem to be mostly focused on 3D printing, have next to no electronics knowledge and their knowledge of high volume manufacturing is dubious (these teardowns are always full of weird errors, e.g. in the Switch teardown they didn't even identify a heatpipe correctly).
