Alas, I have partaken of too much Rolling Rock to write well =p
If they intend to crash fiat, particularly dollars, and are aware that gold will act as a value store during such a crash - as it always has in the past - why would they be selling off gold reserves to the countries you named? More telling, they're selling gold by the ton while they're depressing the price. It really looks like whatever plan they have gives them confidence that gold won't be worth having as a reserve when they pull the trigger.
I can't predict the means they intend to use to keep folks from benefiting from gold reserves, but I can see that they're dumping gold at fire sale prices. Makes no sense to me unless they have no plans to crash fiat, and I reckon it's a good idea to have some PM's just to hedge inflation anyway.
