Nope - the future income from these casinos has already been figured into the stock price by investors - if you think the stocks make a good investment, invest now.
First off, do you even know who is building them? And that they plan an IPO? There are plenty of existing casino companies to invest in, Harrah's and Wynn for starters. Your question tells me you know little about investing. Las Vegas casinos are not what drives profits for the casino companies, it is overseas, especially China. They have all of our money and they gamble like madmen.
When I was I Las Vegas a few months ago I saw a few casinos being built so when they open should I invest in there stock at opening
