Maybe one indicator when prices will start to fall is when companies start retrenching people. Foreigners go back to their countries, locals hang on dearly to their jobs with fear, demand starts to drop, prices will follow.

With the casino opening up in 2-3 years time, big scale retrenchment is highly unlikely. No retrenchment means people still have to work here. Have to work here means must have a house to stay. Therefore either must rent or buy. Conclusion, prices will NOT drop significantly. If you can wait > 5 years then wait, else buy.
