when TN comes online, the cost structure is nearly re-written making many previously expensive options very viable.
They absolutely will not change the battery when production starts in Tennesse. At best, the cell manufacturer will be pressed to tweak the chemistry a little, but remember, they knew all along the issues. Now it's just buying time and mitigating bad press.
I honestly don't expect any substantial battery changes until the new battery technology is unveiled for the 2015 model year. There may be some scrambling with other planned EV's from Nissan, but even then, it's cheaper to write a warranty disclaimer to not cover battery degradation than engineer and tool up a factory to implement an improved battery.
They will choose the cheap path, every time.
