since HOI 4 is fairly certain of being much more capable of non-historical outcomes on every level, i've gotta ask:
is there going to be any chance of expanding, upgrading, and building into the less traditional and more unconventional kinds of land, sea, and air vehicles that were historically used (Submarine aircraft carrier, Hybrid Battlecarrier), not-too-obsolete-but-still-feasible alternatives that were used (Airborne Aircraft Carrier), and even vehicles (as buildable units) that were ahead of their times like the first Sikorsky helicopters like Vought-Sikorsky VS-300 and Sikorsky R-4 (R-4 = first mass produced helicopter, 1942/1944).
it would be a good change from only being able to produce the tried and true vehicles. especially if the AI is capable of trying new things.
