It could also be said that it is all about the US dollar

The US government can not shrink its budget;

The much hyped economic recovery is fake and has not preduced incresed tax revenue;

Therefore the US government can not survive without borrowing incresed amount of money;

China's trade surplus is shrinking, Japan's trade surplus is shrinking, therefore buying support for the US government debt from these two sources are shrinking. And China have actually started selling US treasury bond.

This leaves the Federal Reserve to pick up the slack in buying, aka, QE, or money printing.

This destroys the value of the USD, thus destroys the foundation of global central bank reserves.

Gold will take up the slack in global central bank reserves. Turkey has started to recognize gold as bank reserve for their commercial banks. We will see more of this in coming years.

The proposed BRICKs bank will also serve to remove support for the USD, thus further weakening the USD value.

To say gold price will go down is to say the US dollar will go up.  This is lunatic to say the least. There is no fundamental logic to support a bullish US dollar thesis.
