Yep, I also see that. While the Hong Kong homepage does state "Full Self-Driving Hardware on All Cars" now, it worries me that they updated the order description to specifically state "Hardware 1".
It's all a bit strange, Hong Kong is the only site to show that. I switched through nearly all countries with the country selector on the Tesla site – every other country was updated to show the new "Enhanced Autopilot" and "Full Self-Driving Capability" options for Model S and X, implying that basic Autopilot now comes standard with all orders, whereas HK customers still have to pay HK$19,400 for this.
The HK site still even shows solid white and titanium metallic color options and for the Model X the 60D battery option, both of which aren't available in any other country anymore. Why would they keep extra stock of paint exclusively for HK orders? As if HK has its own factory...
Is this just due to regulatory issues with the stubborn Transport Department? I'll reach out to Tesla tomorrow to check what's going on.
