I think we'd all like to see higher speed charging verified - continuous discharge at that rate isn't so important on a car.
However, if they are planning to use these as buffers for micro-generation, it's a different story. 720A at 12V gives 36A at 240V, only enough to run one of the socket circuits in my place, for example. So if the power density is poor, they lost their advantage in volume and cost too.
