CG7 Black Pearl irons??

[GTV8]

In the new issue of Golf Digest (w\ Arnie on the cover) there was a half page post briefly describing and showing some new irons being released. One of the irons mentioned was the "Cleveland CG7 BP" with milled face and Zip grooves. It showed a 5 iron with the Black Pearl finish. Anyone have any additional info on these? A Google search turned up nothing but a small post on another forum asking the same question.

ps..any benefit or detriment to having the Zip Grooves on a full iron set?

I don't really see a benefit to having zip grooves on every iron because I generally don't want a ton of spin on my 5 iron. Plus you'd never get more than 1 round of a ball.

Good point!! I have a wedge with Zip Grooves and after every full shot I have to scrape out pieces of the ball from the grooves.

I don't have a problem scuffing balls with my black pearl wedge. However, it has developed a hot spot in the center where the blackening has kind of worn off. I don't mind that on a wedge which usually gets beat up looking anyways but it would bother me to see that on every single iron in my bag.
