Effects of "Take Saratov" card?

[Reconvet]

Does the high command card "Take Saratov" have other effects for the Axis player than just getting another - probably major - prestige objective?

The card - according to its ingame text - has to be played before taking either Voronezh, Millerowo or Rostov. This might imply some sort of consequence, for example not getting ordered to conquer Krasnodar and/or Stalingrad due to the fact that he has to commit more offensive resources up north?

The manual suggests that after taking either Millerowo or Rostow new objectives are given automatically: Both Stalingrad and Krasnodar. So has playing the card "Take Saratov" side effects of which the Axis player should be aware of but which aren't mentionned anywhere?

Has this been explained yet?

No. Its just an extra opportunity to get more prestige.
It has to be played before taking certain towns to avoid that the german player can give himself this town as an objective while he is already on the doorstep.
