maybe Dave, They will have this as the main announcement at TMConnect
"Guys, you might have heard about that whole 400 mile pack thing... but what we were saving just to tell you guys, was that this will also include the ability to supercharge!"
Sigh, I am probably dreaming, but I have a friend who would be oh so happy to be able to make use of the Superchargers!
Not sure about announcing at TMC Connect, though that would be awesome. But I can definitely imagine some elated Roadster owners if/when they announce supercharging with the new upgraded pack. Just a 400 mile battery pack is okay but doesn't make (some/most) Roadster owners dance. But a 400 mile battery pack with supercharging... and at a reasonable price (under $25k? I'm not sure about this though)... that would definitely cause some celebration among (some) Roadster owners... not Fango though (j/k).
