Personally, my shot-in-the-dark hope is they take inspiration from Ostalgie: The Berlin Wall and give East Germany a chance to not only remain separate from West Germany and thus prevent the 1990 Reunification, but also gain independence from the USSR at any point in the Cold War provided the DDR becomes strong enough, and maybe even become the new leader of what remains of the Socialist world in the event the USSR collapses.
I just feel like East Germany has so much potential post-1990 for a good alt-history scenario. Mechanics-wise, East Germany might be "weaker" than West Germany due to not having a Marshal Plan for quick growth in the 1950s, and fewer overall provinces to build up (even if Daddy Stalin gives you Polish territory), but every time I've played East Germany, I'm strong enough to stand on my own by 1978 or so. I'm completely resource independent, I have a GDP of around $200 billion, I have one of the strongest militaries in Europe and do not need to import military hardware, and I also have the possibility of becoming a nuclear-armed power.
I'm just saying, East Germany should get some reworked content to allow for it to either take over the reigns from a collapsing USSR, or break free entirely and become an independent Socialist nation. Unlike most of the Warsaw Pact nations, East Germany is definitely strong enough to do it.
