The controller page gives an estimate now (the one someone sent me just said “2027” but that’s something, apparently for some it said a specific month in 2026). Maybe after the first batch of reservations is fully sold the frame page will be updated similarly. Though if the website in the OP doesn’t have some major sampling bias, it doesn’t seem unlikely that the next batch will cover the remaining pre-registrations. Though when that batch will be not even valve might know right now.
