The most obvious change is the wider rim profile (U-shaped) front and rear and the carbon weave change to the sunray pattern from the classic 12K diamond weave pattern that all CCUs have. Carbon spokes look the same, with the rear wheel still having the same ND side spokes as the CCU also. Diamond pattern on the front hub also changed to a different weave. The front hub shape looks the same as CCU. I imagine the rear hub has been updated.
These wheels were out in the open for anyone to see, so apparently no big secret, but I've decided to blank out the identifying items on the rider's Felt bike. 25C tubulars mounted on his bike. I wish I could've asked him more questions about ride quality and such, but the race was about to start. According to him these are "great wheels."
I still love my CCUs and with mine coming in a bit below the claimed 1185g, very respectable for the stiffness and superb ride quality I get from them. I'm not sure whether Mavic would've been able to reduce weight with these new wheels with what seems to be a bit more carbon needed to get the new rim profile, but one can be hopeful.
Added: Interestingly, Team Cannondale was using the classic CCUs on their bikes during the 2016 TOC, although one or two riders looked to have last year's U-shaped front CCU on their bikes.
Anyway, here are a few pics of the "new Mavic CU" (don't know what's up with the super long valve extenders):

The road.cc review set weighed 1,409g. while someone else who took a set of demo. wheels home got 1546g. (863R + 683F). Also, have you taken your rear freehub apart to see if Mavic still uses the delrin bushing? I know they have a new rear hub but I cannot find any info. on whether a bushing or bearing is used. The old design uses a delrin bushing. Thank you.
