but unfortunately they are Selling the results as an ebook at Amazon (clever huh?):

some highlights:
- 10% of self-publishing authors earn 75% of royalties--a statistic that's eerily similar to the income breakout in traditional publishing. (Only about 60% of the more than 1,000 respondents were willing to answer questions about their earnings.)
- Half the authors earned less than $500 in 2011.
- A quarter of books probably won't make back the authors' production expenses.
- Earnings were sharply defined by genre. Romance writers earned 170% more than others, with literary fiction authors earning the least.
- Authors who sought outside help (editing, copy editing, proofreading, cover design) earned more than those who didn't.
- The 29% of respondents who went from a traditional publisher to self-publishing earned twice as much on their own as they did from their publishers.
- The most financially successful self-publishers write more than their peers, and spend less time marketing. In fact, those self-publishers who marketed the most earned the least.
