Jerry, 

Ball flight will be similar (if that is what you're asking).  Other changes include, over 4% higher MOI (more forgiving), a progressive blade length (smaller iron heads as you progress to the shorter irons), and a slimmer looking top-line when you address the ball.  These changes will help the players looking for maximum forgiveness without a large ("Clunky") head they have to look at.  They will also appeal to the past AP1 users, as the forgiveness plays a lareg role in distance control with off-center hits.
