Why? If the US defaults, gold would probably collapse along with everything else.

I figure doc will really like this graph. http://imgur.com/xSOW1NG 

It will rocket, but first, cash will be king for a bit.

Hudes says something about 140,000 tons of gold in vaults on Hawaii. Any merit to this?

In an earlier interview (Karen Hudes (formerly world bank): we need to get new currency like BTC ready) she said something about the stash of the Vatican being much larger than generally thought.

And what's that about american tax dollar going to the UK and then the Vatican?

Exactly, it would fall like a rock, because at the end of the day you can't eat it, heat your house or fill up the car and lots of people offer it, to buy daily needs. Its true value comes after a crises is over. In the absent s of functional Banks any large buy would require some accepted collateral. Nothing else has thousands of years of proven record, only PM's.
Bitcoin on the other hand will most likely spike initially, how it preforms in the long run is pure speculation. It really depends how long or severe any crisis is. In a worst case scenario without communication or power you can not spent them. The longer the current system remains on live-support the better for bitcoin and its price.
Make no mistake the future certainly is with crypto-currencies, but in may opinion it will be wide spread. Different communities will use different money for the same reason they done so in the past.

With PM's you won't get rich, but they may save your arse. With Bitcoins you could get rich, but they want save your arse.
Diversify and look beyond cash, gold and bitcoins.

This may seem counter-intuitive.  But it is what happened, the bond prices went up, and rates down.  Possibly this was because of the way that it was pre-pre-announced then pre-announced and so the reaction was fairly well choreographed.  It was made to seem that if the US T-bill wasn't safe than nothing is safe.
None of the central banks really want the US Dollar to fail suddenly, they seem happier with the slow decline.  If there was a missed bond payment, and technical default (resulting perversely from a congressional effort to cut spending and reduce debt and improve the bond values) who knows what would happen, but I suspect it wouldn't be more bond buying.
