Tourstage has a full release for 2013 including 3 new forged irons the 909 (Muscle Back), 709 MC (Muscle Cavity) and 709 CB (Cavity Back). Irons look great!
There will also be 3 adjustable drivers, a pro model 909 (most likely 400cc or less) and the 709 in 450cc and 430cc sizes. (these heads were shown on the R&A site actually a couple of months ago).
We don't have much else now just some pics from Japanese sites.
