I would like a sword cane. It looks like you have a walking stick/cane get into trouble and out comes a sword.
I was thinking that kinda thing would be neat also. Like a Cane sword or gun. Maybe they could make it so NPCs would not recognize it as a weapon in case you would go into a town that makes you put away all your weapons while in public..Good assasination weapon.
Also, Can we please get a Deringer in the game? That would be a neat variation of a stealthy weapon. I would love to walk up to some Jet head from behind and pop him in the back of the skull with one of these!
For all of you who don't know what a Deringer is, It's a VERY small pistol. Here is a couple pics.. http://upload.wikimedia.org/wikipedia/commons/e/e3/John_Wilkes_Booths_Deringer.jpg
