that map is totally ASB, can't happen nor will it happen. If Germany would annex lands they'd annex the Baltics and Neu Südostpreußen. Luxembourg and Belgian Luxembourg may also be annexed, along with the rest of Alsace. Belgium'd become a puppet and if it is not (highly unlikely), cut up and its individual pieces sold to the highest bidder/given away, Flanders (inclu. French Flanders up to Calais (old Dutch: Kales)) could go independent or go Dutch, Walonia'd go French or German.
Austria-Hungary would not annex that much land either, they'd nibble some bits off of other countries but not as much as is on this map, Venetia (Ger: Venedig) is completely ASB unless they'd cleanse the land.
