Updated Screen shots on allpar
here With all the emphasis on mileage the new Ram is almost certain to get the hybrid drivetrain developed by DC/BMW/GM. It will also get the two new Cummins engines, a V6 and a V8. If Ford/GM/Toyota don't do anything in the mean time Dodge will be the only brand out there with a truck that can pull 10k lbs and get mid 20s for MPG.
After seeing these shots I am cautiously optimistic about the new trucks.
