If you paid via a credit card you could try doing a chargeback with the bank that issued your card. If plastic is unable to refund you, their payment processor will likely be on the hook instead.
That's what I did the moment the "lol sorry preorderers are screwed" email came in. As far as I'm concerned, this was fraud, and I'm hoping I get my preorder (not "investment", not "bootstrap", not "kickstarter") money back.
