Once the units are materialized and proven to have the stated specs, there will be an even greater stampede on orders, and possibly a longer waiting list (during which the difficulty will soar).
That's exactly why I don't think too many will order the $30k rig until the Jalapeno proves itself. There might be a few who do... The Jalapeno is going to take a few months to prove itself. You can't just plug it in, see the 3.5 Gh/s and assume that it will stay that way. It could burn out in 5 minutes for all we know, or it might generate just enough
BTC to pay off the unit, and then burn out.
BFL will offer a warranty on the units. I don't think they specified its length but it should be at least 6 months, if the Jalapeno is working at all you can assume it will continue working that long.
People with lots of cash didn't get that way by foolishly investing large sums of money in unproven technology. You can bet that the smart ones will wait at least a bit to see how this all pans out.
They didn't get that way by watching from the sidelines as opportunities pass by, either. By the time you know the investment is a sure thing it is already too late to profit from it. Being a smart investor consists in figuring out which of the risky investments have the best prospects of being profitable.
It is common knowledge that the stated performance specs are well within the capabilities of ASIC, and it is by a company that is already offering the best mining products on the market. If you don't think that's good enough, you're leaving an opportunity for those who do to profit.
