We have more or less the last big detail about Korra's switch to a digital release, that being what time the episodes would be uploaded online at.
Thanks to Nick on twitter we know that that will be Fridays at 12pm Eastern time which is Noon/Midday
, yes 12pm/12am confuses me too. But it is 12 in the afternoon.
The time seems pretty good, fairly early in the day, so it gives people a big chance to see it day 1 and because it is digital, it means no scrambling to set dvrs or to get home in time to catch a live premiere.
