Good point about the PT boat; let's not forget that the LVT's also operate in water in the game. If I were to guess, I suspect that float and sea planes could be added right now, if HTC decided to. Of course, I could be completely wrong, too. Anywho, I'd love to see them. The float-plane variant of the Zero would be another nice one to add to ports, and how about scout planes off the cruiser?
