Shimano’s new Dura-Ace 7970 Di2 bicycle shifting system is almost definitely the most precise shifting mechanism ever. The carbon fiber brake levers will have either wired or wireless connection to the derailleurs, eliminating bulky and inefficient cables. The derailleur movement is precisely controlled through computer automated movement and servo motors, creating perfectly synchronized and calibrated shifts every time.

No, flawless marketing. You’ll still have to know how to adjust it, and anything using a spring for actuation is going to change over time. My 105s shift f-ing great, never have missed and I’ve the bike for 7 or 8 years now. The bike industry, especially the road bike industry is always coming up with new ways to sell.
