You can preorder a boxed version of For the Motherland at Amazon.de.
Shipping €6,00 in Europe and €14,00 worldwide.
Link: For the Motherland at Amazon.de
Will include exclusive bonus material, new sprites of tanks, planes and ships for Germany and Russia.(Looks like the previous sprite-DLC for that countries. Take a look at the cover.)
I think that can be interesting for those, who prefer a boxed version for several reasons.
Normally you should be able to install it and later edit the settings txt to english.
(If you can't install right from the start in english..)
