I seriously doubt that One Bad Day Mr Freeze is going to have any effect on continuity. At least I hope not.
But yeah, basically. Azrael's a tricky one, because his new origin was SO different, and Tynion worked so hard to try to get him back up to speed, but now Ram V and Dan Watters basically just treat him like the O'neil version. Which is good, it's just wacky.
