That's an awful lot of time and effort just to fall two years farther behind the market. These "refinements" should have been in the original product four years ago. If there's not a surprising new product coming from SRAM in 2013 (besides "Red"), it's not going to be good for the company. (I'm no SRAM hater. My primary road bike carries a SRAM Red/Force drivetrain. It wasn't cutting edge when I bought it and the company keeps falling farther behind every year. Hydraulic brakes? Cool. Old tech MTB stuff. C'mon, folks!)
