Wait until new books are out or start to study now?
I just finished up my CCNA and was hoping to jump into the CCNA:S but I quickly learned that the 554 exam is coming out soon and the study guides not until this summer. Does anyone know how much of an overlap there is going to be? from my brief reading i know that they are adding in ASA Firewalls but what else? should i wait until the official study guides are out before starting?
