I don't expect there to be an announcement for the date. Do you? It'll probably just randomly be published on Sunday.
That's my guess anyway. No offense intended towards the hosts of the contest whatsoever (they've been amazing with the amount of entries received), but it hasn't exactly been strict with specific times & dates. They might just post the results without warning.
At least I hope so because if they announce a date & time then I'm sure it will still be a week until we get it.
I'm actually feeling quite anxious this weekend because we're so close. I keep checking my mail.
