Reading this, I would really like to see them tweak the rules for WFRP3e, using what they learned from EotE where all the existing cards etc would still fit. Then publish one big rulebook collecting the new versions of the rules for all published expansions so far.
So you could just buy one handy book which then upgraded your game to WFRP3.2
Then they could also do some editing work to make the rulebook easier to use for actually looking up rules. (For example, summarize all character creation rules in one place with an easy to understand flowchart)
