new NCLEX-RN passing standard: what's the impact?

hi. i've just joined allnurses.com and i would just like to know what is the impact of the new passing standard issued by NCSBN. does this mean that nclex will be harder when implemented come april 1, 2007? the 2007 test plan seems the same with the current test plan...if i missed something, what's the difference? i'm currently doing first tip of suzanne's plan for nclex so i'm kind of concerned if there are other reading materials i should go through after i finishing saunders.

anyone with helpful info please. thanks.

here's the official info release: https://www.ncsbn.org/1090.htm
