After Park Place completes the Caesars World acquisition, there has been some discussion that they would sell the LV Hilton, and concentrate their high-roller business at Caesars Palace. Might not happen till after Aladdin opens and room supply in LV stabilizes, however.

I don't think any of the major casino operators with properties in LV would be interested, but it will take someone with pretty deep pockets to finance that kind of purchase. Possibly someone like Sol Kerzner, who bought the Desert Inn, or an entertainment-sector company like Bronfman's Seagrams/Universal Studios. Just idle speculation, but if I had to bet between one of the large-cap gaming companies vs. someone else, I'd take the "someone else" side of the bet.
