I'm guessing by the amount of people receiving the same message on the same day that they probably just stopped looking through submissions at a certain point, and sent out a form letter to the remaining entrants; no doubt they had tons and tons of submissions to comb through, and they made it clear in the original information that there was limited space to attend... this would be like an entire city trying to attend a banquet that only seats 30 people.
My congrats to those who were selected to attend.
