This is a serious question, and I promise that I'm not setting you up for anything. I honestly want to know how you imagine the experience of playing this new game will be like. Walk us through it. Don't just say it's going to be like a board game, or like D&D4E, because that's not what I'm asking.
Start as though you were describing a night of gaming with your friends. You're gathered around, ready to play the new version of Warhammer Fantasy Roleplay. The GM opens up the box, unpacks all of the cards and books and dice, and then what? What do you think the next step will be?
What does the GM do? Is he just a card-dealer? As a player, do you wait your turn silently, then flip your cards, roll some dice and knock on the table to let other players know your turn is over? Is it a waste of time to speak in a funny accent while playing this game, since roleplaying isn't part of it?
