I have been looking for a combo set of irons from Titleist (similar to the PMs but they were only issued LH) so I emailed Titleist. I got this response:

We will be coming out with a set of combo irons.
Probably sooner than you might expect. That is all I can say about this
matter.

I'm just wondering if anyone else has heard anything about Titleist coming out with a combo set and what details you might have????
