I don't know WTF you were looking at, but I was just in LV with my Dad looking at property. Many of the brand new Turnberry high rises (they're like 20 - 35 stories) rent for $1/square foot/month and sell for like $100 - $200/square foot. They are absurdly cheap, as most of the other places he looked, and they're modern.
Keep in mind that some have unreasonable asking prices. So I don't know what you were looking at, but the market is falling in LV (my Dad has been seeing price drops over the time period he's been looking).
