I think the move from product simulations/renderings to solely being able to show what the product can do now is a great change. I've been critical about some of the usages of Kickstarter in the past, but this addresses a big part of my concerns.

I do hope that it doesn't keep products that are in a rough state from being able to be successful, though if somethings really that complex that you need to raise a lot of money to have a marketable prototype, let alone bring it to market, I don't think Kickstarter donations are the way to fund it.
