The loop is being extended as we speak, I'd expect more stations to open up in the next few months. Not sure how much existing public transport infrastructure Las Vegas has, but I would expect connecting anything available would be desirable for everyone involved. To my knowledge a lot of the stations are being paid for by casinos/hotels who want to be connected to the network. I assume if the city of LV wants further connection points, TBC will be happy for to build those too.
