Robin Leach has come forward with a couple of supposed Wynn Las Vegas / Encore updates.
First is that Wynn wants to do a BeeGees musical at Encore, which may or may not be called 'Stayin' Alive'.
Second is that supposedly Wynn will break ground on a 4,000 seat 'Wynn Arts Center'.
I assume this would have to be out on the golf course side of things as there's little space elsewhere.
I should note that Leach has not always been the most reliable in the past. As some commenters suggest, it might be prudent to see what unfolds here.
