When NGS will be released?

I have been reading so far that the PSO2 NGS will release together with Episode 6 for PSO2, in this case, Episode 6 will be released in 9'th december, does that mean NGS will release in 9th December too?

No, they said NGS will be releasing next year some time. We didn't even see what Deumans look like in NGS a little while ago, I don't think it's done.

There will however be a broadcast on the 19th of December: https://pso2.com/news/announcements/ngsbroadcast1123

In all due likelihood, at least around March-April if we're lucky.
