From today's "Player's Edge" column in the LVRJ:

Although Wynn Las Vegas does not open until April 28, you can visit the Web site at http://www.wynnlasvegas.com. There is quite of bit of information, especially regarding the amenities (though almost no photographs as Wynn signed an exclusive deal with Vanity Fair), and you can sign the "guestbook" and see if any interesting mail comes your way.
