I can understand why people might be hesitant or mistrusting of such a significant change to their beloved system/setting (and I've been with WFRP since 1986 myself).
What I don't understand is how people can have such a negative opinion without having learned more about the game, particularly when you know more details are forthcoming. Thank god for FFG being a proactive developer, and thankfully we're in the age of the internet where info is abundant. 10 or more years ago, you never would have known about the new direction, no sneak peaks, no threads to gripe on.
This is a major change, abandoning v2 so soon*, and it does look like a major shift in the mechanics, but that may not be a bad thing. I am absolutely intrigued to see the system in action. And I will withhold my opinions about the change until I've had a chance to learn more.
I'd love to see a more in-depth video with Jay talking about the changes, the new mechanics, and showcasing the new components. It sounds like they're working on making the talk from Gen Con available. Which is a great move on their part.
* is it "so soon?" I am not entirely certain. And I bet FFG knows much more about the market (trends, interests, etc) than most of us do. This could be a very good thing in bringing more people to the hobby in general and the WFRP universe specifically.
