As you know, this version of All for One is designed to use SWADE. We've updated the files (and added the new material) to suit the new rules and will be sending the file to edit later today. However, enough has changed that the game mechanic side of the book will need a thorough checking to make sure nothing has slipped through. Mostly that means checking all the stat blocks to make sure we haven't left any old Skills or Edges around.
To that end, once we've got the edited version back we'll be releasing the PDF version first. This gives you time to read the new SWADE rules and help us check any bugs before we commit to print.
Naturally, this means we won't be releasing physical copies in 2018, but the deadline was based on the hope an earlier public release of SWADE. No one is at fault - we just had to select a date we hoped would match with PEG's plans and we were out by a month.
