1. This is not necessarily a hiatus. All we know is Nick pulled the previously scheduled airings after episode 8. Let’s only report on the facts please.
2. Yes NickAndMore is a credible source: they are getting this info right from Nick schedules
3. Korra is not cancelled unless we hear it is.
4. Likely Nick will reschedule the episodes for a different time, probably on NickToons
5. We will get answers at the Comic-Con panel on Friday
I’m not believing it until we get something official it just doesn’t make sense.
