Gold seems about fair valued here between 700 and 1000 USD an OZ so I think it will stay around this range for a good while.
Gold is a well known commodity and hence its value as “money” is an invariant; a bit like velocity of light in physics. It is the paper currencies that rise and fall based on a bunch of factors. So what you are saying is that USD is already depreciated beyond reason so far and hence has no room to fall. That is simply not true based on just one fact: US government will have large (multiple hundreds of billions $) budget deficits and increasing national debts as far as the eye can see; just that alone can assure a falling USD based on unwillingness of foreigners to finance our expanding deficits. (every creditor will some day start to wonder if he will get his money back and if so how)
