Model S 60kWh #P6396
I am listed the exact text from an e-mail from Walter Franck below. Again, this was from March 2012:
This confirms what I have always suspected. I have no reservations about banking on an upgrade in 8 years. If not from Tesla then a third party will fill the void.
Not like its a bet with my retirement stash or anything, but I've seen enough. This will happen and I will take that bet any day.

Honestly, I would never recommend anyone get the 40 kWh pack. IMHO the 60 should be the baseline pack size.
Respectfully, that statement in the absence of any other of 100 variables is somewhat meaningless. This choice depends on expected usage, commuting distance, driving style, and finances among other things.
