Iron Ore’s Meltdown Raises Questions About Miners, page-5

If they actually do squeeze a lot of other smaller miners (which are currently operating) out of business I wouldn't be surprised if one of either BHP, RIO etc. try's to nab SDL with a cheap take over.
Makes sense...
They have the money to build SDL then all they have to do is sit on SDL for the next few years until the ironore price goes up to their liking. Then they have another fantastic money making sandpit to play with with not much competition.
