Wager: Going DRM-free will not harm TOR's ebook sales in a significant way over the first year of DRM-free sales. (Details, as usual, in original posts.)

Spoiler:

If, after going DRM free at or below their current ebook prices, TOR's ebook sales over the following year do not increase by at least 75% of the general ebook market unit increase (Or SF/Fantasy category increase if that is, by then, counted separately), I will cease to advocate for DRM free ebooks, and, indeed, I'll recommend that publishers should keep DRM on their ebooks.

So the likelihood is that prices willl stay the same or rise. As to whether there will be significant losses from casual sharing, the purpose of this experiment is to generate data on this issue. There will be solid results in a year or so. If there are no significant losses, I will change my mind on the issue and switch to urging publishers to abandon DRM.

[EDIT, October 2014: I think it's safe to say that I (pdurrant) have won this one. But stonetools doesn't seem to be active at MobileRead any more.]
