Probably not at least another year or so. When you hear that prices are starting to stabilize is when there will be rumors that Vegas will be taken off the declining market list. One of the main indicator's that MI companies & lenders use to determine if a home is in a declining market or not is the
Case Shiller Index, which measures home values throughout the US. That would be a good index to monitor so you can start to get a feel when Vegas might be removed from various declining market lists.
