Manhattan Real Estate Will Decline in Value to 50% of Market Peak

According to this New York Times article, Looking for Bottom in N.Y. Real Estate, Manhattan real estate prices hav already fallen by 25% according to some people involved in New York real estate.  In the summer of 2008 I told my wife that the Manhattan real estate market would collapse since it was absurdly over valued combined with the beginning of the financial meltdown layoffs.  I believe that prices will end up being 50% or less of the previous market peak.
