Fantastic. Less hackers.
edit: but seriously, its not going to make much difference for sales. People in France and Russia that like Battlefield were going to buy the game anyway, only sales they lose are potential BF newbies that had no interest until they thought their country would be in the game.
Verdun commemoration were not that long from now, Verdun and WW1 is very important for french people, All french gaming forums are getting crazy, mountains of salt are included and first thread about boycott are just poping up
The fact that there are french maps, french guns and equippement and tanks but not the faction, it's an insult for us to pay a 20E DLC to play our SOLDIERS (i insist on soldier because all the equippement is already in the game)
It's like if US faction was a DLC for a WW2 game (ok coh2 did it but it was soviet vs german themed)
