I can understand why some folks don't want guns included, and good points have been made, as it does dilute that pure high fantasy feeling that was in the IE games. I personally like their inclusion however, as I can see them adding more tactical options to combat. Jumping into the fray with a sword and pistol and saving that one shot that can turn the battle would definitely be cool to see in game.
Also, it will be interesting to see how they fit into the lore and current times once we find out more about the setting, as a lot of how firearms themselves feel in the game will depend on how well they're written in.
