In the same boat, unfortunately SP-Tech wants to keep their sales model as pre-order only. Manufactures have the ability to change that and sell out of stock but choose not to because of the less risk to them. All the risk then shifts to the buyer and we see what happens. Please, don't get me wrong, and from previous posts, I think SP-Tech is probably one of the best makers of mining hardware around and I do look forward and eager to see what is on the horizon and future. I think they did the best they could with what they had and believe me, they didn't like the results and specs of their SP30 just as much as the customer's didn't.
For product with a life-span of a maximum 9 months, you can't afford to build it on stock. Look at the biostar 24GH board. They agree it was a trial run, but they came almost 1 year late. If it was an investment to be paid back, it's completely dead. On the other hand, there is a step between pre-orders and stock. It's called build-to-order .. similar with what you do in a restaurant

Sometimes the server takes your steak back because it's "not according to spec", but most of the time, they get it right and everyone is happy with the service.
The technology has to mature for this to happen .. or at least to have a couple of 28nm designs which are systematically improved, a ton of chips taken out the foundries every batch and with a demand not this high to eat all the output (decent 1000 units batch) in a month "on trust" (pre-orders). Eventually, we'll see custom configurations, unique setups which will closely meet the customer demands if they're going to be sold.
