I highly recommend you take a look at THIS THREAD on the RPGSite. A poster named harpy has done some very interesting research on what kinds of projects succeed and which ones fail, using the Kickstarter method of getting funds.
His main point is that you really need to establish yourself to have a chance of making your goal. But even that isn't enough. Read his linked papers and the actual thread for some excellent information.
