no it doesn't, actually. shimano dura-ace track gourp 7710 debuted in 1996 and has not had a single update since. there's no reason to replace it. just like saint works, best brakes in their line-up, ain't broke, don't fix it. sram is the reason things come out so fast now, they don't wait until a product is fully ready, they just release it, and update every 2 years. shimano just doesn't do that, they are a bit because of the competition, but i guaranty shimano would still have us on 11 speed and front derailleurs is sram didn't shake things...
