Thanks! Reading that blog now. I've been voraciously devouring Warhammer and while I know the system is important, I'm more interested in the setting. I haven't run the game yet, so I'll have to see how much I like the system, and it if takes, Zweihander may be a realistic purchase, simply because I like a good system. But I'm all in for the Warhammer experience, so I want to run as native as possible. How different are the editions vs. Zweihwander overall?

I can give you my experience with WFRPG.  My friends and I were primarily D&D players switching back and forth from 1st and 2nd edition before we gave Warhammer 1st edition a try.  The intro adventure killed two characters gruesomely approaching scenarios the same way we would in D&D.  The edition difference is very similar to the way people feel about 1st and 2nd edition D&D.  2nd edition is much more streamlined and cleaner but you find yourself going back to the 1st edition as a baseline and additional detail.  Also, like D&D, I was playing 1st edition before I was actively reading any novels of the line.  It was what the difference between what you thought it was and what you knew it was.  Zweihander feels like a happy medium but also doesn't feel like Warhammer without the setting.  My recommendations:

1.  Never read the novels & expansions and play 1st editon WFRPG.
2.  Read the novels & expansions and play 2nd edition WFRPG.
3.  Grow weary of the WFRPG setting and make your own using Zweihander.  

I think it really comes down to player expectations of setting and system and what everyone is willing to change based on preferences.

4e will be launched at UK Expo at the beginning of June.

/BOINNNG!!!!

Okay then. 4e it'll be. But in the meantime I have all this other material to absorb. WOOO
