Just a quick comment: I have purchased Sailfish X from Jolla Shop. I used a voucher that I have received from the Jolla Tablet Refund, and during the whole process, the only geographic-dependent step was agreeing with the terms of conditions, which in particular mentions that Sailfish X is currently being sold only in EU/Norway/Switzerland.

Indeed, we do not know yet how much different the process is going to be if one will not be using a voucher, and also how the download procedures will exactly go. I think the easiest is simply wait, we should learn that in a week.
