Since 2018, they have released two skylines and two landmark sets. Unfortunately, as it was mentioned earlier in the thread, Lego is moving away from the 'architect', and into the 'landmark'. (Yes, I know they are actually the same). The last 'Architect' set was 21017, Imperial Hotel in 2013. That said, it doesn't mean that the landmark line doesn't have potential. What it is currently is a bunch of famous buildings, mostly chosen because of their height or history. I think that there are some good buildings they could make that aren't 'touristy' but don't really fall under the architect category. Transamerica Pyramid, Turning Torso, Al Hamra Tower, Canton Tower, or the Burj Al Arab.
