A few un-realistic things would have to happen:
1) Hitler would have to give up control of the war effort.
2) Germany would have to rapidly build up it's supply lines for the winter.
3) In the Spring Germany would have to launch an offensive to capture the oil fields of the Caucauses, whilst staying on the defensive on the rest of the font.
4) Encourage the Japanese to launch an attack in Eastern Russia, instead of Pearl Harbour.
5) When Soviet tanks run out of oil launch an offensive to break their lines.
6) Create a strong enough political movment against the Soviets, who fit in line with Nazi ideals and have enough strength to seize power.
7) Force the new leadership to accept large consessions, much like in the WW1.
8) Please note this is pretty un-realistic, and even if this went according to plan there is still a good litely hood that the Soviets will win, or at least score a good peace treaty.
