It's not clear to me that the batteries in the 60kwh version aren't 'reject' batteries that weren't quite up to snuff to support the full 75. So just because Tesla pushed out this update doesn't mean that every car is actually capable of getting the full 75. Where-as the cars sold as 75 are guaranteed to reach that.
I don't know the details of Tesla's batteries exactly, but I'm pretty sure they're just use a ton of 18650s. If too many of them won't hold a charge, then instead of fixing it they can just call it a 60 rather then a 75.
That's a bit silly. I suppose in someways it is nice for the consumer that they have the 60kwh version if they're basically selling it close to a loss with the hope that you'll pay for the battery upgrade, but obviously it begs the question why the 75 model can't just be the same price.

Because Tesla would make less off of each 75, which is no good when you need cash to expand operations. Have to squeeze every dollar out of each sale, manufacturing and R&D costs money!
The 60kwh has been discontinued after tepid demand. The 75kwh is the cheapest Model S one can buy today, but that wasn't true for a few months 60kwh was up for sale.
