Still no news as to format for WOT but since it's from Tor/Forge is will almost certainly be DRM-free and will probably available in both mobi and epub formats. Same is probably true for Baen's nominated Larry Correia novel Warbound.
Also, Tor/Forge has an alternate download link for the 2014 Campbellian Anthology on its website, in mobi and epub format. This anthology contains all of the shorter Hugo-nominated works by new writers as well as exerpts from the eligible novels.
Here's the link:
