Define shortly? The 70D was introduced April 2015 and 90D in July of the same year. Then there's the 75 pack which is even newer. Then there's the whole debate as to whether the 90 is a true 90.Tesla is not interested in selling batteries or letting people upgrade. The exception is 90 to 100 only because the 100 came out shortly after the 90 and they don't want to piss off recent 90 owners.
I see the whole upgrade thing as someone that was on the fence as to which pack to get but regretted the decision later.
