While funny I doubt this is the case. I doubt they would have even mentioned the product let alone the potential availability of it without already having run through a few phases of product testing in the market through the NSI program.
No doubt this is likely related to part/component availability or just general logistics nightmares of the world right now. Perhaps some software aspects are still being worked on but if they didn't already have an idea of the physical devices being landed in the US they would likely have no idea of the availability date. Either way, I am sure so many people had quite the media headache when the leader of the company flirted with a launch date.
