I doubt one person will buy them all for market price again.  The last guy got burnt and has like 1/3 of his money. 

That said, these auctions are actually good for the ecosystem I think.  It gives some big players a change to dip into the Bitcoin coin system.  There are some super rich people that can't be bothered with buying a few Bitcoins at a time.  This is an easy way for them to pick up 10 million worth of Bitcoin at once and not stress about it.
