Smart Batch 3 owners would re-sell their pre-order for truckloads of cash.
They aren't going for that much - their pricing where much higher just a few days after they went out of stock.
Now, with BFL shipping (slowly), ASICMINER delivering units 3/4 days after purchase and preparing a new deployment, plus others players willing to enter the market, the enthusiasm is much lower.
Add to this that there are still batch #1 customers without their units, and that not a single batch #2 customer has received yet a tracking number... And you will understand why the value of batch #3 preorders has diluted. I don't think you will get more than a 20% markup on one of those, and you would sell it to an anxious newbie.
If Avalon suddenly starts to ship batch #2 with tracking numbers and promises shipping of batch #3 very soon... Well, then maybe you could unload your preorder with a 200% or 250% markup.
