Tried searching for this but couldn't find anything. I backed the game very early on and snatched up one of the Collector's Editions. Recently I noticed that the Obsidian edition has been popping up on Steam and other places which is advertised with the first three DLCs included. I am just looking for confirmation whether Collector's Edition purchasers are going to get these DLC included, or would I be better off spending $20 to get the backer season pass at a discount prior to release?
