Should I wait for the 714 AP2's?

I have been playing the miz MP 57's for about 4 years now and its about time for some new irons. I have been looking at the AP2s and I know the 714 model will be coming out this year (November I heard). Is there going to be a significant increase in technology with these or is it a safe bet to get the 712's? Has anyone had the opportunity to play the 714's yet? I'd greatly appreciate any feed back!
