As we know from history, Stalingrad was the beginning of the end for the Third Reich in the East; the loss of VI Armee and the subsequent loss of many of their best armored units in the unfortunate Operation Citadel forever took away the German initiative and signaled the eventual victory of Soviet forces.
However, what would be the result of a German victory at Stalingrad, before the point that the VI army is worn down? I am not going to suggest that as a result it naturally follows they will win the war, but what if they remain a potent force?
Of course this calls into question whether Hitler would accept one of the peace offers that Stalin sent out through third parties. Just wondering what your thoughts are...........
