The internal combustion engine still has a lot of advancing to do before its completely discarded, for sure.
I don't see this technology ever making it to market though. Special pressured oil line through the crankshaft, rod, wrist pin and finally into the piston to actuate the VCR, with a separate external (in this case) oil pump? Pretty neat just that anyone ever pulls it off in a prototype test engine. This is not a new idea, but kudos for Honda to keep it alive and kicking. They should combine this idea with the variable stroke length concept:
