Well, I wouldn't put too much faith in Sony's claims without measured proof right at this time. Being a P.Eng I'd have to view scientific data upholding their claims before I could quote it. Be and diamond are the stiffest materials we have in relation to their native weight. Beryllium has a molar mass: 9.01u and hardness of 5.5 Mohs. Acoustic propagation is typically 12600m/s- 12890m/s, 14000m/s longitudinal velocity, natural diamond is the only material that can exceed that by any amount that I've ever seen. If there is a better material though, I would be open minded to it.
