Their format follows their Scorpio reveal in both timing and in both content. It would be a stretch to indicate that they had nothing else to show, when they didn't change up their reveal from Scorpio. Which part was a CGI render? I'm almost 100% sure all of that is real recorded footage. Scorpio had a CGI render.
There are (what looks like) 2 optical outs, 2 HDMI/2USB + 1 ethernet on the rear side (blue mobo). If this is revealed in the final version, this board was very far along.
An unknown port on the opposite side (I'll call it the debug side) that I am not familiar with (if it is even a port - in 1 shot there is something inside it, in another it's empty), and also a USB type B interface port.
The blue mobo has a different configuration from the green mobo. The green mobo; with the limited knowledge, the ports are on the same side of where the CPU is placed; this is opposite to the blue mobo.
The idea that all of this is pure CGI renders/not work in progress seems very unlikely. Just saying. I get skepticism, but basically you're saying that either MS wants to throw everyone off, or MS is nowhere close to their 2020 deadline for next gen.
