In Computer Gaming World's preview (this is the magazine that was suppost to have the Demo exclusively, the one that was backed up by EA) they don't list any other weapons...
There will be more guns... This was posted on EA's website... "Access to over 21 historically accurate World War II era weapons, including Thompson submachine guns, Mark II Frag Grenades, .50 al mounted machine guns, flame-throwers, and "sticky bombs"."
Is canada in the game?, well of course not, its an american game but for single player skins, if there is , it would be pretty cool, we had good guns back in WWII.
