I mean it's literally that obvious. Toneri said: The gate the Nue opened has been sealed. Jougan's turn won't be coming up for a while. However it's only temporary"

The way it is phrased suggests that the Jougan is yet to come. Considering that he refers to Nue, Jougan seems to refer more to a being than an eye specifically. of course, considering the actual mark of the Gozou, it could refer to that too (it had a giant eye on it).
