Pro Pack as far as anyone knows is still not out yet. Curious Labs info about it leaves tremendous room for improvement. I'm not sure what you get for the money either. Perhaps Curious Labs is taking the position that if you have to ask what it does it isn't for you. There are probably a number of beta testers on this sight that are sworn to secrecy. If tradition holds they will be released from their vow just before or at release and can fill us in.
