Mazda was working on laser ignition plugs for the rotary engine, and I think when push comes to shove laser plugs might get widely adopted to squeeze out an extra 1% or whatever in fuel efficiency, because they don't take much space in the combustion chamber and can have multiple ignition points to reduce that unburned fuel loss. But if you're talking a lean burn engine, the multiple ignition points means the temperature will also go up slightly and you'll have more NOx to deal with.
