jimnms: I'm talking about the extras included in the collectors edition like the soundtrack, art book, etc.
The extras are not included with the Enhanced Edition because you already have them in the original game, ie. the extras are exactly the same so they didn't include them twice
To clarify for others playing along at home:
~ [If you have it] the original Divinity: Original Sin extras (soundtrack, artbook, etc.) are
exactly the same as what is included in the Collectors Edition, meaning you will have a "standard" edition of Divinity: Original Sin Enhanced Edition on your shelf because you already have the extras in the original game
