Could it be under $10k, sure, will it be at least $5k, no doubt, likely to be around $7k, very possible.
So yup, very likely to be around $7K.
I'm sure it will look pretty darn cool, but as I've said, so glad they made the smaller/cheaper one and that I got it on initial pre-order, as there is no way I could afford this one. Between our dropping exchange rate, shipping, 10% GST, 5% duty, etc it would be around $10K AUD total.
Outside of that, an ES of 500 is I think a bigger fantasy then the series itself. Given that the first one at half or less of the price only sold 200.
