Maybe Killian made prototype Extremis nano-weapons for Mandarin's rings?
Personally I just think the rings aren't gonna have any special powers, theyre just going to be symbols. I just think it would look silly on the big screen have someone shooting lasers out of their rings given the very tech based Iron Man world.
