If it helps, there's a PDF that clearly lists the rewards now:
https://dl.dropboxusercontent.com/u/7001919/Matrix.pdfThis Kickstarter will play a huge role in determining how extensive the future Delta Green line will be - all those source books mentioned in the survey a few days back? They won't happen at all if the Kickstarter doesn't reach those levels.
Arc Dream has made it a point to get books out to KS backers before retail customers, plus backers will probably see new versions of the rules before anyone else.
Darren I give 50% of staying there - the game needs some 'old hands' since Alphonse is gone.
Nancy is beyond a doubt feral by this point. She's gone to her people.
Curtis, the leader of the cowboys, is probably a martyr for the cause at this point. His partner is probably leading the charge now.
Matthew is probably alive, but in hiding or otherwise 'retired' - possible adviser for PCs.
Wu is probably high up in the legit organization.
Mason and any other prominent friendlies are probably gone. Too many enemies and too little protection from DG.
