It seems likely that they'll be required to AUCTION them off through an approved process rather than sell them themselves on an exchange.

And they probably won't do that until they've convicted "Dread Pirate Roberts"

There are enough of private investors willing to buy without crashing prices on the open exchange. Financially, it'll be a good deal for both a buyer and a seller. I heard SecondMarket's BIT (bitcoin investment trust) can't buy new bitcoins fast enough from private hands to satisfy the demand.
