It's an interesting rumor, I kind of like an increased focus on digital codices, and this app might solve the problem of no interactive codices on Android devices. Holding a book in your hands is always nice, but automatically updating rule changes makes up for it I think.via an anonymous source from the Faeit 212 inbox
There is some talk about GW still working on a new App. It is supposed to launch with the new website next year.
It will be a full-fledged App allowing online purchases and, maybe more interesting, allowing GW to better enforce DRM for their digital books (i.e. the purchase of an ebook from GW will be linked to the account and can only be used through this account). The bright side is that it is supposed to include an army builder (this might be build into a new format of digitial codex), the downside is that it might be the end of the regular printed codex book. Collector's editions are selling so well that GW is considering to only offer the limited edition printed book "while stocks last" and the ebook version.
Orcs, supposed to be released after the launch of the new website, will be a kind of trial run offering all three versions of the codex (Collector's edition, new style digital codex and "normal" codex) with a big campaign to persuade customers of the advantages of the digital product.
In this regard, actual army lists might disappear from the Collector's editions. Instead they will include a version of the digital codex. This is considered to get rid of the FAQ/Erratas, those will be entirely solved through database updates on the App.
