CityCenter will get done - with Dubai's money. Fontainebleau, too. But just about everything else is in danger of being abandoned, or at least postponed for several years.
Las Vegas isn't exactly dead - it's just readjusting to realistic revenue projections after several years in Speculative Fantasyland. ;)
I have heard of the Fountainbleau but I know nothing else about it. Where is or will it be located?
