Will the new / streamlined rulebook be posted here on BGG??
You can get a plain text of what I assume is the backbone of the "new" rulebook over at Pinebox site.

This clarifies the rules and puts everything in plain English. The AEG rulebook was very thematic but the period language made it a bit confusing, particularly for non native speakers. I'm assuming the Kickstarter version will add some fancy art, some fiction etc.
Hope this helps!
