Panzer Campaigns teaser guessing thread

[Green]

If ComradeP is correct, it could be Poland is being worked on or it could be that they have a very large Master Map that they can carve out whatever campaign is being worked on.

 
Anything is possible but I doubt a game on Poland is likely to include Vienna and Daugavpils. The possibly of a Poland '39 game has been mentioned in the past but the map required for that would not need to be anywhere near as massive as the map I posted. A large master map of part of Europe is a possibility but given the amount of work it would only make sense if there were specific plans to use all of the locations mapped. Perhaps there is some other explanation or perhaps the city depicted is not Daugavpils, in spite of the resemblance?
