I read that e-tron article, and with the doubled battery size, that sure does read like a Roadster. We know what a good place to start that has proven!

Crash-worthiness of big-batteried cars has been a hot topic of late, a fact addressed neatly by Audi. The A3 employs a shut-down system that decouples the electric drive system from the car’s power supply in any collision significant enough to deploy an air bag or seatbelt pre-tensioner, meaning the battery would cease feeding power into the motor.

Exactly. I'm pretty sure the Model S does that already too.That doesn't address the situation at all. What happens when there is an intrusion into the battery compartment that causes thermal runaway on one or more cells? Cutting the exterior connections does nothing in that situation.
According to an Interview of Handelsblatt with "Audi-Entwicklungsvorstand" Ulrich Hackenberg (dated 19.12.) Audi will shortly decide whether to build an R8-Etron. The decision might be taken before the end of the year. Hackenberg is in charge of developments since July 2013. He stated that the original car did not have adequate range and that in his opinion an electric sports car needed a range beyond 500km (312m).
To reach his range target evidently a new battery will be needed. To go from here to production with a sufficiently proven battery system will very likely take some time. One year looks optimistic - even if they "just" have to get where the Roadster was 5 years ago.
Citing recent advances in lithium-ion battery technology...
I'd love to know what new battery chemistry Audi is using.
So Tesla does the heavy lifting of driving battery advancement and the laggards join later.

Can anyone think of a production electric car with over 150 miles of range that didn't sell about as fast as they could be produced?
I just don't know what numbers Audi is looking at to decide that they can't make money on this.
When is another company going to offer a serious EV that actually competes with Tesla?
