First of all, big thx to Neal for the very clarifying interview.
Only type VII and ending in 1943. I am pretty sure that the game will come with steam and dlc.
In my Empire Total War game i have so far 5 contents installed and so they will do with SHV.
Wanna have the type IX ? No prob, its only 2,99 € via credit card or paypal.
On the other hand this business model has a great advantage for the customer: patches come very quick because a non working game is the death of sales figures.
