Fairly in that both games were trying to drag us roleplayers kicking and screaming into the future instead of living perpetually in the early 80's and unfairly in that warhammer 3rd was not a roleplaying game.
I agree with this. I was dreading a 'cleaned up' version of WFRP 2, or something based on the 40K line, even though I know it's been very successful. I had a lot of fun with WFRP 1 and other games using lots of crunch rules like DnD back in the day. But - although it's possibly become so big and popular that it's now cool to hate it - White Wolf's Vampire, the Masquerade changed all this for me. If you bought all the thousands of books, there were an awful lot of rules you could add, but at it's heart, the system was simple, expressive and full of variety. Plenty of other (Indy?) games have also come along with wierd, wonderful and innnovative rules (Try Unknown Armies for the brilliant madness meters!).
So I was very pleased that WFRP 3 set out to radically redesign the sytem. I was less pleased with some of the outcomes. For me personally, there are still too many rules. Combat being a good example: I'm not interested in 50 different cards for 50 different actions. I'd rather have a 'combat' skill/attribute/talent/whatever and use narrative storytelling to describe whether the fighting involveds shield slamming, twin strikes, etc.
As a GM I also find that there are far too many rules for NPCs. I personally would like everything I need to know about an NPC (rules mechanic-wise) to be able to fit in a short and simple stat block - with possibly a few bullet-pointed special rules. And I'd like to be able to resolve NPC actions as quickly and simply as possible, without referencing cards, books, etc.
I also would have preferred the books to have been a lot denser when it came to setting material, even if in practice, a lot of the material that was written for scenarios for older editions would never be accessed by players. I also was uncomfortable with the tendancy to emphasise more of the high fantasy setting of the wargame over the low fantasty grittiness that WFRP is famed for. Although that said, it's easy to romanticise material published for past editions: there was plenty of rubbish stuff published for WFRP 1 and 2. I miss the black and white pictures too. In fact, I think the art goes some way to explaining why I feel that WFRP 3 was higher fantasy than previous editions even though I suspect that empirically it's not necessarily true.
So, I agree with Commoner: the game doesn't suck, even though it's not perfect.
I think it's unlikely there'll be a new edition published any time soon (i.e. for years). If FFG really don't want to continue to put effort into supporting the game, they can use POD supplements to keep it on life support. But if it dies out because of a lack of customer interest, I can't see that they or anyone else is going to go to the expense of producing a new edition until some time has passed.
