In case you're unaware, Babble is being delayed until January 2013:
Barring a Mayan crisis, it looks like Babble will be shipping to Diamond on 27/28 Dec, available in stores early Jan!

But, word has come from Com.X that adapted files have been submitted to Comixology and iVerse ready for Apple approval and subsequent publishing for handheld devices and desktops - and we should be seeing Babble hit the digital shelves on the same day as the print release! Needless to say, links will be added to the "Where To Buy" page on the Babble site when they become available.
