Oh man

I would be happy if they slid the dates ahead and started at Dec 5 instead. At least then I would be assured that Luminous arrived before Christmas. I chose Dec 12 because that's 4 weeks after the Resistance revamp and Thanksgiving is in there. KMS had their Resistance revamp on June 20. Prelude followed only two weeks later for them on July 4. We may get lucky and have that short window too. Thanksgiving is early this year (Nov 22) so if we had a 2 week interval like KMS did, then we would get Prelude on Nov 27. I don;t think that will happen, though. I think Tempest will firmly begin in December, though, with Dec 5 being the earliest possible date. I think they need the extra time to finish debugging it. They probably have it tentatively scheduled for Dec 5 with Dec 12 as the fallback date. I think they will go with the fallback date.

Of course, this is all just my own speculation based on KMS patterns and the only two facts we know from Nexon directly. I am quite confident in it, though.

Gotta remember that GMS loovvvvessss putting patches together into one big cluster. My prediction(minus dates) Is this:
Prelude access to Pantheon Magnus etc (not allowed to fight yet), Luminous Mid-night release, Kaiser Midnight release before Christmas allowed to fight Magnus, AB Release after New Years, server check to activate Hyper Skills. Or Hyper skills from the very start. Kanna and Hayato in November or Feb, mxed in with Evolving world and Warrior+Mage Hypers.
