I have been waiting for the US keyboard to come back into stock.
Your eyes are not fooling you, the US keyboard is not listed.
I have emailed the site (in China) and they are very good at replying, however, as of last week they were waiting to hear from RIM on when, or if, more keyboards would be available.
I suggest emailing them yourself. There may be some power in numbers.
They usually respond within 24 hours.
(BTW - The black US keyboard has only ever shown up under the 8800 listing. The 8830 is the VZW version of the 8800 and is only (stupidly) available in silver. You can however purchase the black case (thereby ditching the Verizon logo and the black keyboard making it more readable in low light. I hate the blue keyboard.)
