Some big changes are in the works for the Las Vegas Strip. The last major opening was Wynn Las Vegas just about a year ago; now it's time for even more. A few years from now, the Strip could have some new additions.

The Stardust Hotel is one of the many sights that will be gone soon - perhaps as soon as next year. Filling its spot will be a new resort called Echelon Place, one of many new urban developments with high-rise condos. You'll be seeing many more high-rise condos along the strip in the coming years.

As old Vegas gets even older, locals are saying goodbye to the more memorable landmarks, and hello to newer ones. The Wynn is the latest project to sprout up on the Strip and it's look is described by visitors as stunning.

"Especially when you ride in on the highway, and see the gold color to it," said Las Vegas visitor, Charles Glaze.

But the themed casino-resort boom, which started with the Mirage in 1989, may be giving way to an entirely different trend, the high-rise condo.

"The only thing that people can be certain of in Vegas is that change is constant," said Erika Yowell of the Las Vegas Convention Visitors Authority.

Yowell wouldn't look into a crystal ball for us, but did say high-rise condos will be a big part of the skyline in the Vegas future.

"The condo hotel item is working in Vegas, because the kind of person who's coming here is the kind of person who can afford a third, fourth or fifth home," she said.

Folks at MGM-Mirage, who are building the urban project known as City Center, say one high-rise condo tower sold out nearly 600 units in a matter of months. People we talked to on the Strip say they understand why.

"I like that, at night you can see around you know," said visitor Arnold Gerloff. "I guess it would be good to have someplace for people to stay and be here on the Strip, so condos are good."

So for a city in constant flux, it literally is out with the old, and in with the new.

Besides the Stardust, rumor has it the Frontier and the Riviera might also soon be gone, and we all know about the Tropicana, whose future is also in doubt. But even if those places do shut down, there should be no shortage of ideas for what might come next.

The hotel-casino boom isn't exactly over. The LVCVA says Las Vegas should have another 25,000 hotel rooms open up within the next four years.
