We'll see a lot more of these as groups that had only ever made one prototype raised millions or tens of millions pre-selling products whose bill of materials cost they did not even understand.
Not to mention how they get taken to the cleaners by suppliers who can see the public side of the project's finances and make rapacious demands on the cost of that BoM after the fundraising closes. Projects would be well advised to have hidden backers as well, to prevent all the money from being in sight, even if they get multiple cost quotes before the Kickstarter.
