I found some of the business arrangements interesting, though maybe not surprising. I think those are the real new details of this release.

First, they'll be producing 50GwH of packs, but only 35GwH of cells; so they'll still be dependent on external cell manufacturing for a sizable portion of the packs.

Second, that it sounds like Panasonic will basically own and run the cell part of the factory; as opposed to Tesla or a joint venture purchasing the equipment and making the cells themselves.
