There's a load of new info in that article TEG found. For example:
The Leaf will include an "ECO" mode, which could extend range about 15-20%
Nissan is working with AAA to carry special charging packs that can recharge sufficiently in minutes to get the car to the nearest charging station.
To meet California law, the Li-Ion batteries will carry a 10-year, 150k-mile warranty. The pack is rated conservatively to maintain a 100-mile range after 10 years, retaining 70-80% of its initial capacity.
The manganese oxide Li-Ion pack weighs 480 lb.
The Leaf has a drag coefficient of 0.29 Cd [this really caught my eye, as it's the first time I've seen the Leaf's Cd data released]
Nissan's plan for future EVs? A light-commercial van slightly larger than the Ford Transit Connect, and then a high-performance Infiniti four-passenger car.
