I heared about that a month ago from a very reliable source too but for me it is hard to top off the TC3, a car that is a bench mark of what is considered a new design today for other manufacturers. I can think of some mods that the tc3 can benefit slightly from like what they are doing now ie. moving the batteries closer to the center.
Anyway, I think if they try to stay close from it's current design whould be a good thing.
If it is a radical design from a different planet it would be a risky move.
Whatever it is. Just AE's reputation of producing great prducts will surely make me get one or two or three....
