So actually he's right. Xbox Series S will only ship with a "High Speed" HDMI cable. It has a 2.1 out port though.
Only the Series X will ship with an "Ultra High Speed" HDMI cable.
Also Xbox has confirmed nothing extra is included with the console in box (like a game or Game Pass etc.)
But the S's cable in box is not capable of 4K30 HDR video, High Speed maxes out at 4K 24Hz.
Basically, HDMI cables are:
High Speed = 1.4 (PS4 and Xbox One shipped with)
Premium High Speed = 2.0 (PS4 Pro, Xbox One X shipped with these)
Ultra High Speed = 2.1 (PS5 and XSX)
