Sandy Petersen's Cthulhu Mythos for Pathfinder 2nd Edition

I saw this came out today. Do you think it might make it into FG?

That does not have a simple answer, but likely no. Smiteworks does not create ruleset modules in-house. They are commissioned works.
A small publisher like Peterson Games might not already have any agreements with Smiteworks to have material on the FG store to begin with. If you are interested in trying to make this happen, the point of contact for Smiteworks can be found in this post, I think.
Based on this post for the 5e product, they look to still being working on getting an agreement in place, however
