DCT has been out for a while in other cars, so its not new.
If the C7 had adopted the 10spd out of the Camaro ZL1 I would be driving one of those right now instead of my 7 speed manual Z06... The 10spd auto in the Camaro ZL1 is a superb transmission for being a regular ol torque converter slush box. It runs more like a DCT trans from what I understand(2 gears always engaged).
