The devs have said this exactly however, that a German 1936 tank will be identical to a British 1936 tank, and that if they tried to give them "historical stats" for base models it would drive them and the players crazy.

Thanks for the video, which I had not seen. This is what is said at 5-6:00 minutes in:
Q. WWII had tons of different models of tanks and planes. How do you ever choose . You can't possibly have everything
A. It's a mix between what people want to see... Panzer, Sherman...
Q. Will the models be purely aesthetic difference, or will there be a gameplay difference, say between German and..
A. The intial tank levels, so if you are comparing 1941 tank for Germany and Britain - that on the base line is the exact same tank. It's only flavour, this is an abstraction. We and the players would go crazy if all the stats are totally different. But there are things that will happen with each nation. That ... I haven't actually announced how that will work yet. We will be talking about that diary coming up in the future. You will have different stats on them. When the tech is done there that will be a base line for everyone. I don't want to talk too much...
Take out of that what you want. If you believe that Panzers will be the same as Shermans then that's your opinion.
I think the medium tank
chassis will have the same stats for Germany and USA, but that each country will nearly always be applying a different variant to that base tech level. And you BUILD different tanks. And you EQUIP your Divs with different tanks.
Real difference in stats on the battlefield, not just a flavour name.
1. Your engineers/scientists develop the base tech chassis
2. your general staff decide on the finished design which will go into production
3. the economics ministry allocate factories to build the design
4. the factories produced the finished tanks which go into an equipment pool then gets allocated to Divs
5. the Divs go into combat with the new tanks and this generates combat experience
6. the generals in the field ask for changes to the design
7. go back to 2
It seems to provide a quite realistic model to me. Without the devs going crazy trying to change the base tech for each country, even though we know the chassis and airframes etc. were in real life different. For Germany read Guderian about the development of the new tanks in 1943. There were various models presented to the general staff and they could choose between them, or even ask the designers to make modifications.
So I come back again to the OP. Japan can build Zero's which have a much larger range than their equivalent at the same tech level which are produced by the Allies. And not by artificially researching drop tanks that boost every single plane they produce say 20% regardless of type/model. They can produce some ground-based twin-engine fighters with no intention of ever using them in long-range missions and have no drop tank tech or other range boosting method applied. Instead they can beef up their armaments to use them as interceptors to defend the home islands from strategic bombing.
My only change of stance comes from what might Podcat announce. Maybe they won't carry forward the variants from one tech level to the next. Maybe Japan will have a Mitsubishi tech team that just knows that the ideal thing for JAP's Pacific strategy will be to present to the Naval Ministry plans for long-range carrier capable fighters. And another tech team will offer you something else and you get to choose. I like that idea even more. Guderian gets offered choices between tanks from different manufacturers and he goes with the more complicated design with great armour and gun, puts it into production too late to get many on the battlefield, and then they are not very reliable and breakdown, so the Pz.Divs are still largely attacking with outdated tanks that can't possibly resist when the SOV counteroffensive starts.
