If you mean conforming - ALL our wedges will conform to the new rules (which are a little complicated).
What will the Tour Groove due?
I am by no means an expert on this so anyone reading this response that knows more, please go ahead...
The governing golf association (i.e., the 'powers that be' ;-)) has changed the rules / spec's regarding grooves for irons. As mentioned above, sometime in 2010, equipment used by tour pro's will need to adhere to the new rules. Sometime later, the rules apply to the next level of players, and at somepoint, manufactors / resellers are supposed to stop supplying equipment meeting the old groove standards.
I do not know that anyone necessarily wants the new grooves -- actually, I guess some do as the rules were not arbitry (perhaps they were ;-) My understanding is that the primary impact will be when hitting from the rough--the newer grooves will decrease the accuracy, and therefore make it harder on individuals hitting from the rough. If I remember correctly, the concern is that on tour, pro's are going much more for distance than accuracy, especially when hitting from the tee box. The current iron grooves are so good, it allows them to recover from most/many shots that fall outside the fairway. Thus, by there being a greater penalty for inaccurracy, it is believed that the pro's will focus more on accurracy (i.e., hitting the fairway on their t-shot).
Golf magazine recently (last several months?) performed some tests with pro's and amateur's using today's grooves and the new spec'd grooves. I seem to remember that when hitting from the fairway, there was a wider disperson pattern for the new spec grooves but there was not a tremendous difference. There was a much greater impact with shots from the rough.
As far as what's changing, most of the grooves on recent high-spin wedges are squared or u-shaped. I believe the new rules limit the groove shape to v-shaped and limit the depth of the groove. The square & u-shape grooves have two benefits: 1 - a sharper angle of the edge that contacts the ball; 2 - more space in the groove to route moister & other stuff away from the ball (limiting the groove depth impacts the moisture 'routing' capabilit as well)--this routing effect primarily comes into play when hitting from the rough.
Point #1 reduces the amnt of spin some but it is not the most significant issue -- thus Golf mag's article that showed from the fairway, there should not be too much of an impact. Point #2 (moisture routing capacity) is apparently the bigger issue, especially in the case of wedges. Mid & long irons depend on the face of the iron compressing the ball in to the ground and the decompressing of the ball aids in its speed / trajectory. With wedges and low irons, there is a greater dependency on the impact of the club face pushing the golf ball along. Moisture between the ball and club face impacts the quality of the contact & the control one can impart on the ball through the contact. Thus, the smaller grooves will have less ability to route the water, and therefore the contact with the face of the club is not as good.
Anyway, if I am off on any of this explanation, please enlighten me ;-)
