This is confirmed today by the official prices for the US, France, and Spain. Stateside you can expect to pay $799 for the device, while in the Eurozone the price will be 699 sans VAT for the single-SIM model. You then add to that the specific VAT amount in your country.
For example, in France the final VAT-included price is 838.80 (single-SIM version) or 874.80 (dual-SIM), while in Spain it’s 845.79 for the single-SIM model and 882.09 if you need dual-SIM functionality. Note that the aforementioned price for the US is for the single-SIM Elite x3, and it’s unclear if a dual-SIM iteration will be made available in the US at any point.
Now the only thing that’s still a mystery regarding the Elite x3 is exactly when it will become available. Hopefully that’s set to happen soon.
