Color me not just skeptical, but damn near dismissive:

Reviving The PBY Catalina For Modern Warfare Is This Company’s Goal

I fully support the manufacture of newly designed, modernized PBY “Catalina” flying boats. Damned things were awesome 80 years ago; had I buckets of money, I’d fund the program myself. But *this* program does not inspire a great deal of (i.e “any”) confidence. All they show are a few *very* low re and simplistic CG renders of a modernized PBY… lacking the  braces that kept the parasol wing from snapping off during maneuvers. I know materials have advanced a lot since the 1930’s, but come *on,* that design just don’t look right without those braces.

Recall that just over a year ago an Australian company said they were going to remanufacture the Grumman Albatross flying boat. The last “news” update to their website was December of 2022.
