I was hoping for an update on these and found a video at Tacomaworld
There were also two more posted by the same user when I dug in a little. Enjoy!

Claims from the tech link, which is the best of the three I think:
20% tougher sidewalls
Longer treadlife on and off road (15% on road, less chipping off road)
Coregard technology (tougher sidewall rubber from KR2 racing tire)
Stone ejectors inside tread to help prevent stone drilling
Side lugs designed for airing down
Mud-phobic bars to help release compacted mud (not that I think they will be that great in it)
Mtn snowflake symbol still included
"significantly increased snow traction" on par with dedicated winter tires
