I am empowered to advise all of Western Europe of my Archduke's feelings with regard to the Burgundy and France situation:
1. Austria will not allow Burgundy to swallow France; we will willingly ally with England, Spain and France, and likely Denmark, to see that this does not happen.
2. France should be allowed to struggle to reconquer her natural lands. The Archduke would be plenty happy with a France that consists of the lands South and West of the Seine. A Burgundy which includes all lands between the Seine and the Rhine is acceptable.
3. When and If the lowlands people decide to revolt against the cruel overlordship of the Comte du Bourgogne, ideally there will have to be a choice between continuing play as the Comte, or switching play to the Staadtholder. After all, there is no reason not to allow Holland to form as expected; to reward the current player of Burgundy, there can be compensation, such as letting the Staadtholder take everything north of a certain point and then having the remaining provinces ramdomly decide (with decreasing degree of probability as you go south) to go with the Staadtholder or remain with the Burgundian dukedom.
After all, for all we know, England, France, Spain and Venice may solve the problem by removing any significant Burgundian territorial gains.
