This can be a good thing. Veldrin, or someone with a remaining copy of the master docs, could go through and difference them with the printed cards. The ones that are mechanically different could be put into a special section of the FAQ. The ones that are the same could be ignored. Thus Fantasy Flight is happy - their cards are safe. Also the players are happy - they can see at a glance which cards have changed. Also, we're extra happy because now every new rule is centralized in the FAQ, instead of being spread out over 3 documents.
Well, but I would like to compare the original cards to the translated cards in German, others probably want to do he same with other language versions. I have the old Master Documents, but not the ones for the expansion of course.
