Today I checked some of the commonly played Northrend instances, and these are the results:
Naxx = All mobs except bosses are level 60-61 elite as they were in the original version of the instance (before BC). Bosses not scripted properly (no spells)
Ocurus = Not Spawned
Nexus = Working properly although bosses do not use abilities. But they do have them scripted.
Utgarde Keep = Not able to enter? Let's me go in, then kicks me back out.
