It depends. How is your hybrid set up now? My 'fastest' hybrids have my hands at the same width, and my back at the same forward lean as when I ride the hoods on my drop bar road bike... Just like most cyclists mostly do. There's virtually no difference in aerodynamics or speed according to my ride times. Tires, gearing and bike weight can also be the same. But yeah, get a new road bike, it will definitely be fun!
