We're all waiting for pricing information Patrick...I'd expect it to be disclosed prior to the end of the first quarter 2012 as U.S. manufacturing will be starting around then.
By way of a guesstimate, you can look at the ratio of US to Belgian Roadster prices and apply that to the US$ cost of the Model S, with the battery of your choice.
To give a second data point, divide the US$ full price of the 'S' by the $/Eur exchange rate and add on the applicable import duty and VAT. I think that import duties for cars are EU-harmonised at 10%.
