Appreciate you accepting my apology, we’re all good.
If you haven’t already, make yourself a coffee and read the mental Colosseum thread and see just how polarising this theme has become.
I always welcome new sets/subjects even if I don’t personally feel them. I loved the Trevi Fountain and hoped for more releases in this vein (such as Notre-Dame or Sagrada Familia), alongside more modern architecture but I’ve long since given up any hope of this.
An updated (with newer elements and more refined building techniques) FallingWater would be fantastic but zero chance, especially since ART left LEGO and took his relationship with the FLW Foundation. He subsequently agreed a license for his own new company (Atom Bricks - Tom Alphin a EB member here did a great review here)
Even recent sets which have been impressive (Trafalgar Square springs to mind) have had very questionable (I’m being kind) architectural merit and have focused more on “tourist sightseeing”.
So at this point, I don’t really know what to expect anymore. The Forbidden City guess seems to make a lot of sense. Don’t think anyone had even mentioned Seattle before you raised it, but if I’m being honest, it’d still be a typically lazy set for LEGO to dial in, just as an updated standalone Eiffel Tower would be. I’m surprised they didn’t already go down this route after Statue of Liberty. Iconic landmarks are easier as there’s only so many Skylines you can do.
That said, there’s still a number of interesting and even iconic skylines still to me made. Personally I’d like to see Rio de Janiero and Liverpool amongst others.
