My experience with DLC for other games has been mixed. Bungie used to be good about releasing their map packs at exactly 2am PST, but that's not a requirement and other companies don't have to follow it. If I recall, some Oblivion DLC wasn't released until past noon PST, so you might have to wait. And at the anon commenter who said it was 12:30pm EST, I don't know what EST you're in, but it's 10:40 pm CST for me, so there's no way it's 12:30pm EST for you, that would either be 10 hours in the past, still on the 25th, or 14 hours in the future on the 26th. Currently it is 11:40 pm EST, as of posting this comment.
