XTR coming December,XT a bit later.I think if Shimano want to stay in the game they will have to release a wireless group soon. Or no high end bikes will have Shimano if they all removing the cable routing..... it's like a big F-U to Shimano
Full Wireless ala Sram, also new brakes, same cassettes as today.
Supposed to be real good and priced below Sram.
