Titleist doesn’t time their releases to the competition releases. …Why should they? More information will be leaked as they seed the next release on tour. Expect some information at the PGA show in January and a March release. Assuming the pattern stays the same.
Note the 620 irons and T400 have not been updated. I’m only guessing there is a next release in process for wedges.

PGA Merchandise Show in Orlando coming up end of January. Many brands show new releases at that time.
Maybe we will hear something around that time. "Just speculating". SM9s are such great wedges and doing well. Hope to be there to see what is available.

I hear they are coming out just about 2 years before the SM11 wedges.
