Word on the street (never actually saw any hard data) was that the new Corimas were better than the Mavics in 5 spoke. But then factor in the good old Team GB. For all of their research and development, they are running a super special 3 spoke. 'nuff said.
Addressing another comment above, Look bought out Corima. Perhaps that was the catalyst behind the update. I tried to get a line on a Corima rear disc here in Australia, but they were non communicative post Look takeover.
Then, comparisons form track to TT/Tri use of front bladed spoke wheels are futile. Outdoor road racers deal with all manner of wind speeds and directions. Fighting with a bike to control it constantly over the course of a 90+km bike section is mentally and physically draining when it doesn't need to be. Despite what such riders might save in aero, the handling aspect well overrules those gains and so road use aero fronts are a compromise of aero and handling. Basically on the track, especialy indoor, all we really need to worry about is aero ~ a-la the front disc
