I played there a couple of weeks ago. If they have decided to close it, it was recent. The room was full, in fact they had to limit the tournament to two tables because the rest of the room was for live games. They have removed the section of tables that was the higher limits and replaced them with slots and the room (and the rest of the hotel) has a very dirty feel. Of course this was just after I came from Borgata so there might be a little PPOV there.
The website for the poker room is still up if that's any indication.
