I don't think the "current" Prius battery costs will go down. If anything, I believe they will go up. Why? The third (next) generation Prius will be powered by a lithium-ion battery, versus the current nickel-metal-hydride unit. Since Matsushita Electric is reducing the number of nickel-metal-hydride Prius batteries produced, I don't see the impetus for the price decrease.
Of course, since I can't tell the future, this is just conjecture, and slightly off topic at that.
