Nope. Zatanna and Rocket have consistantly been referred to as the Newest Members. Their designations are before the newly revealed ones. It doesn't mean that they'll be new characters, but it does mean with about 99% accuracy that there will be two people getting bumped to the League in some way. Which still classifies them as new Justice League members.

The 2 new designations are 27 and 28. There could also be the possibility of them becoming members between Happy New Year and Summit. Doesn't necessarily mean they're inducted in the last episode.
