If today's Fed announcement doesn't start a serious Gold rally, nothing will IMHO. My fear, is the announcement today will kick start market and people will pull their money from gold to buy into other undervalued equities.
The fundamentals would suggest that all this money pouring into the US economy will devalue the currency and drive gold up... I'm just not 100% sure fundamentals and supply/demand mean anything yet in these markets. More and more people talking this is good for commodities... so that is a positive.
Tomorrow will be a telling day... spot price up after hours.
