I seem to be finding a bunch of cool infographics recently, they are the future of communication (warning, sarcasm may be in affect here). It is always interesting to see what the status of sales, especially e-book sales. Personally, I see the e-book becoming the new paperback within a few years, and I also think that backlists will be all e-books. What will be really interesting is whether authors will be the one controlling their backlists or whether publishing houses will want to grab hold of those. Then it becomes a case of what rates are paid on backlist, because the sunk costs are a frontlist issue, so you would expect a greater author share of sales (although it could be argued that sunk costs are sunk, thus trying to recoup those costs as part of the sale price is bad economics).
