I think conventional airplanes have reached their limit. That does not mean airplanes cannot become more efficient. BWBs (Blended Wing Body) are more efficient than traditional aircraft. They have increased payload and fuel efficiency. Kind of like a merging of a flying wing (B2 Bomber) and traditional swept wing (747/777).

"Blended wing body has lift-to-drag ratio 50% greater than conventional airplane." http://en.wikipedia.org/wiki/Blended_wing_body
Boeing/NASA are currently exploring BWB with the X-48. http://en.wikipedia.org/wiki/Boeing_X-48
