I also want that! But I assume we won't get it today! Mercenary Edition does state that we will get it, but it does not say when. Up to now we had only clear announcement about the game it self, not other goodies.
From the store:
On the game's full release you also get the Elite: Dangerous Mercenary Edition, loaded
with digital extras:
• A digital download of Elite: Dangerous for PC (and Mac from Spring 2015)
• Your very own Eagle fighter ship docked in a secondary location in-game
• Exclusive pack of ship paint jobs
• A ‘day one’ ship decal
• A digital players guide
• A digital concept art book
• Plus loads more digital goodies to be announced over the coming weeks.
• Plus an automatic permit to visit Sol or anywhere in the Solar system without having to first earn a reputation with The Federation.
So at least for the Beta buyers it is pretty clear that we should get Digital players guide TODAY. That's what I payed for.
