Actually, Toyota will
Actually, Toyota will maintain 2,300 employees in California, including its oldest manufacturing facility in the US, TABC (which supplies parts to the factories in Texas and other US locations, as well as Japan).
Also one correction: California is indeed (back) in the running for the gigafactory as state and local officials have been in discussions with Tesla for several weeks now. A possible location is in Imperial County by the Salton Sea, which is not only a natural source of lithium and the location of a first-of-it's kind factory that will extract lithium from geothermal energy (brine), but also an area that is a major center of geothermal, solar and wind power, has ample and cheap land, access to rail, is within close proximity to Tesla's manufacturing in Fremont and of course had access to skilled labor from the most technologically advanced state. You can also be sure there will be the same lucrative benefits and great green regulatory environment that helped spawn Tesla to begin with and allow it to flourish.
