There actually has not been any official offer for a meeting with the witnesses. In fact, I don't believe there has been any direct contact, unless you think a post on Steemit or a Cointelegraph article is contact.
Also, what has been proposed on March 6th doesn't sound like a meeting between the new Steemit ownership and the witnesses at all.
So, in my opinion, as of right now, there is no meeting.
