Had to be fuzzy; since I (nor anyone else) has any details and this was only mentioned in passing by the EM people at the P5 reveal, it's about as clear as can be stated.The meaning of that is kind of fuzzy. Hey, if they are going to fast build 25 E series, and the intent is to refine tooling design and methods, isn't that like a mock assembly line? It's got both more and less meaning than you might think.
