I read in an interview that given TW's love for guns, Mount and Blade 2 will be in a June 6th, 1944 setting. The primary focus will be beaches Sword and Juno. DLC content is already being planned; and, the whispers in the hall indicate that it has something to do with Eastern Front and a playable sniper class, ala 'Enemy at the Gates'.
I predict a June 2013 relase date. Makes sense and allows them to capitolize on the historic day of days.
