If they look to launch before Ep 7 I would think the compressed time frame would limit a book to fluff, some gear/ship ideas they've had, a few new species, and some modular encounters. A stretch would be maybe a new universal spec, but that's about it. Then again, they may have been brainstorming this for some time and were just waiting for the word from the mouse and lotsa ideas ready. Who knows.
Noticed the F&D module went to print yesterday. Maybe we will get some info updates here.
