Over at the Comics Alliance there is an interview with Online Marketing Manager Matt Parkinson about Dark Horse’s digital plans:
CA: Will digital comics purchased on iTunes prior to Dark Horse’s January launch be compatible with the new software? Will the current slate of titles eventually be removed from iTunes and replaced with new versions that integrate with the new service?
MP: Once the Dark Horse Digital Store launches in January, apps previously downloaded from the iTunes store will be eligible for update, free of charge. The updates will happen in small batches with new versions of our comics that both support the iPad and allow in-place registration for the same title in our bookshelf (as allowed by licensors). So all those individual DH apps you’re currently carrying around on your device will go away once you make the update, then you’ll be able to house all your DH titles on our bookshelf app.
