Wrong all around. Thunderbolt is a superset of HDMI. Thunderbolt is ALSO a superset of miniDP.
Mac laptops haven't had Ethernet for many, many years, except via the Thunderbolt or USB adapters, both of which will still be possible on this machine, too.
Yes, the SD card reader was left out.
Wrong on USB ports; it's absurd to suggest that "100 out of 100" keyboards and mice plug into USB-A. Most such products these days are, in fact, wireless, and those which aren't can simply use a very very cheap USB-A to USB-C adapter.
Connectivity includes AirPort Extreme (802.11a/b/g/n), Bluetooth 4.0, Gigabit Ethernet, a Firewire "800" port, two USB 3.0 ports, a "Thunderbolt" port, audio in/out, and an SDXC card slot.
Just to point out that assuming "most wireless HID devices are Bluetooth" is likely incorrect - a huge amount of the devices I see come with a dongle of some kind, that plugs into... (you guessed it) USB A sockets.
