battery prices

This is still an unproven technology. Don't forget the maintenance on an BEV will probably be a lot less than an E-Rev. I know the range issue gets people, but one of these days, we're going to see the price of li-ions drop much like megabits in hard drives.

Battery prices are not going to plunge like computer chip prices. You can't reduce the number of atoms needed to hold electrons in a battery like you can in a transistor. Batteries will get better and cheaper, but they won't get much below $200-300/kwh just on materials costs alone.
