Hi Tobias,
according to the same "inside info" I got earlier this year, it is believed to be an "ordinary" album of about 12 songs, not an earbook. But I think there will be kind of Deluxe Edition as well, maybe even more than one. BMG won't waste a chance to grab some extra bob when it is field-tested marketing approach now which proved to work well with other mainstream releases. The format of Deluxe editions may be whatever, including Blu-Ray and Vinyl boxes, I presume. Depends much of CR nanagement which I still know nothing about.
Best wishes
Andrey
