Guess the airport we just got the sat images for (and boy oh boy it is hard these day to get those legally and for a acceptable price) and you get it for free. If it is not guessed in 10 minutes I will be very very disappointed.
Toms explanation is 100% correct and if we want to keep on selling boxed products (and we do, they actually still sell very good) we need to have dates somewhere in the system. But these dates are often placeholders and should be taken with a grain of salt. In my schedules Brussels is by no means seriously delayed (of course we did reboot the product because a previous projects did not turn out as we wanted).
And that closes the discussion on release dates.
