You're right, except I think it's ok anyway because there's an expectation with Kickstarter projects that they will take time to actually produce. People know it will be a long wait for the final product, but get excited over the process itself - it's fun, they feel some ownership of not just the product but the process, the ideas are cool, and the whole crowdfunding thing is still a novelty. Then there's the doldrums, but that's ok because it's expected, then additional rounds of excitement as milestones are reached, and finally the crescendo at the end. Expectations are managed from start to finish, the only thing the project absolutely must to do is deliver something worthy of the original mission statement. It also helps if they keep a constant stream of communication and updates flowing to their supporters. Seeing the progress is almost as emotionally rewarding as getting the final product.
