If someone is willing to pay at a higher price than the price now, why not just slowly buy at the exchange.. or through the miners..
Miners already have contracts out. The biggest miners, that aren't pools, will be lucky to make 100 coins a day. So that would take over a year with the difficulty rising like it is.
Buying slowly at the exchanges will be quicker, but the slippage is still horrible when people start front-running you. Meaning that the volume will pick up as you buy, the price will rise as you buy, and this will encourage other people to buy. So you will not get even close to dollar cost averaging about $750 per coin by the time you get 29K BTC.
There are ~12k btc to $700 at bitstamp alone. Someone could buy it NOW If he's willing to pay >=700. Why hassle yourself with the auction and wait long for the auction date if you could buy it NOW at the exchange? You could also spread your funds across the other exchanges to get it cheaper. And I checked, bitstamp's volume for the past 3 weeks and it's at ~170k btc. If they started buying since the SR auction issue started, they would have got the 3k btc that they want without causing much price bump..
