I thought I saw a post on here earlier that eluded to a rumor of new iron models dropping in the fall. Have no idea how much faith to put in it as I'm definitely not in the know.

No one know for sure if Titleist will still use the T series names or include changes to the other models yet. They keep that under wraps until tour validation which used to be right after the PGA tournament in August. Now that the PGA is in May, they could start as early as the end of July, all depends on how ready they are. They know pros do not want to mess with adjustments until after the last major. Typically will be a few months after tour validation before pre-order and release to the general public.
