I’m in the US. Reservations opened at 12pm May 8th, I queued up by 12:01, got my link to purchase last Thursday with the controller arriving a few days ago. Based on that and considering there were likely a lot of reservations placed over those two days, my gut says that you might be waiting a while, unfortunately.

It works, I launched a rocket on it. Subjectively it feels 20-30% slower to do stuff than with a mouse and keyboard, but once I cooled down and adjusted to it instead of trying to speed through stuff it was good!
