I have a response from the Black Library saying very clearly that an ebook version of the Militarum Tempestus is not planned. With each release now, we have seen different types of releases. One release will be digital only with no print, the next ipad and print only. It feels like these releases could getting a little chaotic on what format they will be available with.
What I think customers want, is some stability. Knowing what format they will be able to keep their book collections in is important. Some things you cannot get in print, and some you cant get in an ebook.

Thank you for your email. We have a small Digital Editions team who work on the Codexes and digital content for our game systems. As such the Codex: Militarum Tempestus is only available on iTunes. We do not have any current plans to produce this title as a standard eBook, but we will endeavor to bring out as much of our content out as standard eBooks as the schedule allows.
Many thanks,
