I'd be happy and amused to see the PBY-5A and H8K2 'Emily' added in the same patch like the SBD-5 and D3A1 were, only this time the Japanese would be getting the better plane.
I wonder how many of the guys giving a "+" or otherwise advocating for the PBY-5A would actually end up spending a lot more time in the H8K2 'Emily'?
The point would be it's probably THE iconic flying boat of the war, even if others were more capable. And just like any other "hangar queen," people would still fly it even if something better was available for no better reason than that alone.
Of course, a PBY with some of the Black Cat armament packages would be REALLY fun to play with.
Something I'd always thought would be cool is that a PBY (or other patrol plane) that gets within a certain distance of a CV group would put the boat's icon up on the map so long as it maintained contact with the task group. That would give such aircraft a specific Main Arena usage right out of the gate.
