Ask for a refund and ye shall receive, up until they time they are shipping. One person has already asked for an received a full refund that we know of already.

Also, refund will be priced according to dollars, not BTC (ie, you receive refund say $6,000 in BTC or cash, w/e, not the original amount of BTC you put in, because they've already sold that original btc for cash to pay for the NRE and devices.)
