No, the only thing different about that limited edition Japanese version was that it had Federer's signature on it and that it had his wider string spacing (4 crosses at PWS) and it was sold with his strings of choice. It still had the same longer handle pallet as the retail version. It was still just a nCode 90, which Federer never used as Federer used the K90 underneath his nCode 90 paintjob.
