I went searching because, as I said I thought they were coming next week. Could find no mention on the NBC news site. There was a Camilla story there though. The ABC news had a short article, but I had to scroll about a foot down the page to find it. I would expect that People and Page Six would have something, that is what they do. Report on the rich and famous tabloid style, though nothing really holds a candle to the tabloids you have there.
There is no Royal frenzy here in the US. Nor are we insane. They are like any other celeb to the majority of us. Someone to see if you can, but only the die hard royal fans would get on a plane to try and get a glimpse. And I say this as a long time US royal watcher.
