It's no great secret that the world of publishing is changing. What is a secret is how much. Is it changing a lot? Has most of the change already happened? What does the future look like?
The problem with these questions is that we don't have the data that might give us reliable answers. Distributors like Amazon and Barnes & Noble don't share their e-book sales figures. At most, they comment on the extreme outliers, which is about as useful as sharing yesterday's lottery numbers. A few individual authors have made their sales data public, but not enough to paint an accurate picture. We're left with a game of connect-the-dots where only the prime numbers are revealed. What data we do have often comes in the form of surveys, many of which rely on extremely limited sampling methodologies and also questionable analyses.
