Interesting new game direction, really I thought most Triple A games wouldn't even touch WW2 let alone WW1. So this is indeed a breath of fresh air in this quite stale FPS world of Battlefield and CoD. (OverWatch of course is another wonderful game but it interacts differently than CoD, BF, or Halo even in my opinion)
Dice has been good with games and have a good track record, so I'm not too inclined to worry about "Historical Accuracy" as everytime we play VideoGames we often have to Suspend our Sense of Belief anyways. So essentially as long as Germany/Austria looses they can't really mess up the History that much.
Weapons! Combat! Vehicles!
We've seen plenty of games that have great mechanics with weapons and battle tactics with Trench Warefare (Verdun anyone?) and Vehicle usage in Battlefield has always been fun (Jets, Tanks oh my!) The only thing now is though is to implement Mounted Horse combat (I doubt this will be a major part of the Multiplayer) so I have no reservations for Mounted Combat as their success in WW1 was few and far in between.
The Armour Badass with the Machinegun and the Frightening Tattooed Woman riding her horse and the Tank rolling through trenches with Bi/Tri planes flying around the Battle field only excite me with all potential
