I think it will definitely be interesting to see that 10 speed Allison. Ford stayed with the 6 speed, as the size/mass of the components needed to handle the torque available vs how much space it would take up.
It'll be interesting to see
1. What the final numbers are (torque)
2. How physically large of a component it ends up being
3. If it ends up having a high rating and commercial users squeeze every once out of it, what it's longevity ends up being.
4. They should certainly be "best in class" for fuel mileage
