This leads to a few questions that should be answered as they may become relevant.
First, what metric will be used to determine that they are "cheaper than the competition"?  Will it be based on price per gigahash?  Or Watt per Gigahash?  Or some other metric?
Second, if it is Watt per Gigahash, then we will need clarification on final specs (1400 watts per 1 TH/s or for a full X-3)
Third, how will this be handled?  You promised!  But so far your only guarantee is that if you drop the price on your website, which any sane person, even  if orders stop coming in, wouldn't do as it would create a liability of more X-3's owed.  So really, that is just manipulative talk, as you do not have to drop the price for any reason, even if your competition is priced better.
