Nice.
They're dividing the drive before the middle axle so both rear diffs are receiving equal power so you'll always have at least one wheel on each diff turning, unlike a truck.
They mentioned making use of traction control which is no good to those of us that are stuck in the past (or, should I say, clinging on to the electronic-free days of reliability and repairability!) But that shouldn't matter too much; you'd be unlucky to get three wheels on separate axles hung up at once and then it's nothing a diff lock or two couldn't fix.
Even with three open diff's you'll still have an advantage over a 4x4.
