Following this snafu, I was able to confirm with several insiders about the actual ports on the current early iterations of the hardware. Keep in mind, these may not be final and are subject to change but do come from multiple people familiar with the hardware.
As it stands right now, the series X features, on the back of the hardware, two USB-A ports (of the SuperSpeed variety), ethernet, a single HDMI port, optical audio, and a power connection. There is also another port on the back that may be used for debugging but there wasn't an agreement on the nature of its functionality. The image at the top of this post shows a basic outline of how those ports appear on the actual hardware.
Also, on the back of the device are openings for air intake as well; all of the ports are located on the lower half of the hardware. Keep in mind, there is also a USB-A port on the front of the console but for now, it looks like Microsoft is sticking with the older USB style port.
I do wish that the series X would use Type-C as that is where the market is headed and is more user-friendly but that's not currently be used on the early hardware iterations. As always, these ports could change before release but that's what I am hearing the series X is using today.
