Once we have a real space industry I imagine there will be progress in areas like ion propulsion. You'll still need chemical rockets with >1 thrust/weight ratio to get off planetary bodies, but ion propulsion could be much better for long haul trips.

We've already had a lot of recent progress with ion propulsion. Not only are many satellites hybrid or all-electric, but NASA has launched several probes with a lot of maneuvering delta-v of ion thrusters.
