as long as we are just speculating here, here's some food for thought:
Is this going to be a card dependent system? or, are they just visual learning aids?
4e D&D is obviously card dependent. there are so many things going on, especially at the higher levels of play, there is no way the average joe can learn it all. keep up with everything he can do.
Now this WFRP has cards. but is the system dependent on it? would it be possible after a few plays to internalise and remember the actions/rules?
memory experiment: i have seen one card. the ranged shot card. I know from the mechanics that one axe is a success. 2(or was it 3?) axes does plus two damage. two birds gives me a free manuever( what ever that thing is), and two skulls pulls an unengaged enemy into melee with me.
how did i do?
this my friends is the benifits of a visual resolution system. you can pick things up quicker. if you have been playing for years and you are good at math and remembering text, and you have plenty of friends that "think" the same way you do then this new edition probably isnt for you. probably wasnt designed for you. its for old farts like me and the new guys.
