Operation Citadel fully succeeds

[ReconGuy02]

Let's say that Germans succeed entirely as they planned, and by late 1943, with destruction of 2,5 fronts, they managed to stabilize the frontline around Don, so that it resemble May 1942 frontlines except for Kharkov Bulge, with Red Army unable to sustain any kind of offensives greater than corps level until early-mid 1944. It's obvious, that Germany would still lose, but I have 2-3 questions .
When would the war end, who would take Berlin, and where Iron Curtain would lay?

Warning: Please, do not grind this discussion to a halt with explanations why German 9th and 4th Armies could not have done such task. I am fully aware of the reasons why they could not have done better. I am more interested about aftermath, than the process.

As long as the Soviet Manpower issue in the late war period isn't made more severe due to the loss of the Kursk Salient, I don't see the Germans being able to hold off the Soviets.

Berlin is not going to the Wallies unless they turn on the Soviets at the last minute (which is borderline asb). It was decided beforehand at the Tehran Conference if I'm not mistaken that East Germany would go to the USSR.

Those two fronts had 1.800.000 men. If they are lost, and there is no liberation of Ukraine and Belarus swathes in late 1943, Soviet manpower shortage would probably be more acute.
