Looks like Expedia has leaked out some extra photos of the rooms at Encore, the companion resort to Wynn Las Vegas.

We get to see the entry way, bathroom and most interestingly, the sitting area. You can see in photographic detail how the 'suite' is divided - a wall with a cut-out for a TV that swivels between the two rooms.
Thanks to reader JK for the find.
