Titleist Clubs

I know that the new 913 metals just came out but when do the next irons, wedges, and putters come out? And what is the cycle time for metals? Every 2 years?

i believe that the new irons come out the end of this year, and that they are on 2 year cycles.

That would be my best guess.  I know for sure that Titleist specific clubs are released every two years, so the irons should be out sometime in November.  For the wedges and putters though, I'm not quite sure when they come out with the new ones.
