Hi Billy

It is my understanding that Toyota has dropped the idea of the two regular Prius batteries and is going for one lithium ion battery now. EV speed will increase to 62mph, but Toyota is talking about only selling these units to Governments and Fleet purchases only at first. This means you and I may have to wait a few years (2012?) before they're available. The good news is Toyota may sell the regular Prius with a design that can be upgraded easy with the more costly lithium plug-in battery at a later date. I think Toyota is going to offer this upgrade to compete with after-market plug-in companies and sell the new panasonic lithium batteries Toyota is part owners with. All this will help drive the cost of the lithium batteries they make down. Hopefully Toyota will have the possible upgrade design before I buy one for my wife.
