Some people have replied to specific variants of this, but to put it all in one post:
(Spoilers for literally every currently implemented German path in TNO)
Speer: Speer isn't a "Dengist" - if anything he's a
very orthodox Nazi. But because Bormann has that niche locked down, he's had to adopt the students and dissidents from Nazism as his support base, something he's very unhappy about. Depending how the player (or AI but I've never seen AI Speer do anything but implode) juggles the various factions, the endings are
four:
- Speer is puppeted by Nazi conservatives, and this can basically be considered a variant of the Bormann ending. Can happen any time your regime stability dips too low and isn't restablized in time. No real content as of yet but Europas Narben could change this.
- Speer loses to Schorner during the Slave Revolt. Goering without Goering.
- Speer is puppeted by the Gang of Four, and democracy begins to return to Germany. However, this is not the Wholesome 100 Ending it has been made out to be - Russia is still gearing up for war with Germany for Moscowien, and the Go4 are going to be blamed if Germany loses that war.
- Speer outmaneuvers both these factions and purges them. Nazism remains the dominant ideology of Germany, and Germany is still strong enough to remain a superpower for at least the rest of the mod, even if it's long-term trajectory is still probably towards collapse.
Bormann: Has been slightly changed from his original incarnation. Bormann is willing to make
token reforms to keep the Reich going, but nothing that would seriously challenge Nazi ideology. At the end of his term, Germany has been painfully stitched back together and seems to be on the road to recovery - only for Bormann to be diagnosed with cancer and realize when he dies, Germany will collapse into Civil War all over again. The Red Army Faction is also starting to be active towards game's end, and it's strongly implied TNO!Germany is about to enter it's equivalent of the
German Autumn.
Goering: The inverse of Speer, actually. Goering is somewhat of a reformist (and even reaches out to Speer early on, an offer that is promptly rejected) but is forced to champion the militarist faction because Speer has already occupied that niche. This route can only end in two ways:
- Goering's mad dash to revitalize the German economy via more war comes to a screeching halt when Germany meets opposition it can't steamroll, the bottom of the German economy falls out and Germany quickly collapses into another Civil War.
- If Goering somehow fails upwards to the point war with Japan or the United States is on the table, Goering and Schoerner are powerless to resist a new clique of ultra-militarists who are so deluded they believe Germany can actually win this conflict. Nukes fall, everyone dies.
Heydrich: Heydrich can either be a good little puppet for Himmler and hand over enough nukes to start a nuclear war, or decides to cut his strings and wages an apocalyptic war against Burgundy. In the first scenario, Nukes Fall, Everyone Dies. In the latter; Nukes Fall, Burgundy and Germany Die, and Heydrich ends up committing suicide because he believes he's failed Nazism as an ideology by slaughtering so many Aryans. Either way, Germany has been reduced to radioactive rubble.
There's also Speidel's Germany and the DSR but neither are currently implemented and will probably undergo multiple changes before they are.
