Then they've got to either be doing a very, very small run or their schedule [b]will[/b[ slip (an unfortunately common occurrence with KS stuff).
Schedule will slip anyway. It's not really "anyone's" fault, its just the nature of Kickstarter projects that most people doing them don't have a good idea of how long things take. And they're more willing to let deadlines slide for a better product.
My own KS project is over a year (nearing 18 months) past when we said it'd be available, but quality skyrocketed as a result. Our delivery date was based on the pipedream of having to do a tiny print run of like a dozen copies that we'd have pushed through Game Crafter. We had over 700 people want a copy. As a result, we found a publisher and are doing a very large print run, and negotiations took time, as well as completely redoing the artwork,* so delivery got pushed back.
