I'm also curious too, to these Q&A. I have some feeling, that the NCwest already got the answers from the Chief Developer, but for any reason they didn't post it on the forum.
Vali used to say, that they want a big surprise and want everything in all together.
So, I think might be we will get the answers too only when the Lindvior released or when we already know its release date.
It wasn't so much questions, so a Chief Developer are able to answer to all of them in 1-2 hours max.
If he or NCKorea would not care about another regions, they wouldn't post Q&A thread or something. In Korea the "respect" and "loyalty" are more important things than in the western world.
But, I don't know, really that why is it necessary to keep back any information to the last second about the new update.
This is a huge and really interesting and good update, what 99% of us wait since we did hear about it.
