Hybrids are most likely going to be a big revolution - but honestly, unless there's MAJOR strides in the domain of electricity, a purely-electric large-scale trans-sonic plane like the 747 or 777 most likely could not happen. For that to be possible, one of two things would need to be accomplished: an electric jet engine (which would require an insane amount of electricity most likely) or trans/supersonic propeller propulsion (which I THINK has only ever gotten close to in WWII's fighters like the Mustang - and even then, it was still 200km/h slower than a 747. But maybe, just maybe with modern aerodynamics (and our understanding of aerodynamism/fluid dynamics at transsonic or supersonic velocities) it would be possible)
