Model X on September 29, 2015. Fall seems to be the major release keynotes. Is there a specific time of the year that Tesla makes updates we can forecast? Apple iPhones always get released in the Fall and we can count on it. Getting ready to pull the trigger in January 2016 but I can wait if something better is brewing. Maybe 85 battery going obsolete and they're just sticking with a 90 to streamline production for Model X and S? Any historical data on Model S would be appreciated. If none, January 2016 it is.
