Battery package /size conjecture

[insaneoctane]

... If they did offer 55 kWh, how many do you believe would feel the difference to a 60 and pay that extra money? It will only mean that tesla will ship 5 kWh extra battery to several thousands of cars without getting any money for it. I believe that they will offer 60 kWh for the base model at $35k.

I have to acknowledge this makes some sense. I don't know how attractive an extra 15 or 20 miles would be. hmmm.
