> As an American, I will order this phone as soon as it’s available to me!

It won’t be. From the time of their first phone the company actively made the choice to not support the US market. There’s the obvious spectrum difference and cost to certify, but the real reason they don’t want to touch it is litigation risk on patents and whatnot.

Even if it's not sold in America, you might still be able to buy it and use it, how well that'll work depends on the spectrum compatibility of course.
