yuan revaluation good for gold?

With all the talk re a Yuan revaluation being imminent, I am wondering what effect this will have on the gold price.

The consensis seems to be that the gold price will rise if the Yuan is revalued higher. The performance of gold over the last couple of weeks where it has risen while the USD rises seems to support this. However the performance of Gold Shares and the COT report seem to point to an imminent pullback in the gold price, is it possible that gold will derive no benefit from a revaluation. I have also noticed the relative strength of the Aussie dollar over the last few weeks, could a rising yuan lead to a stronger Aussie dollar as commodity prices would be cheaper for the chinese to buy which would keep demand strong. This situation would be very bearish for Australian gold producers.
