They'll make the model Y in Fremont because once the Model3 line moves to the new cast superstructure process enough space will be freed up for both lines to coexist because of their shared parts. The other factor is the strong market acceptance of the cybertruck means they'll need space for that and Sparks Nevada is a better choice because it won't likely share many parts with the model3/Y other than the motors.
