[2022] NDA question

There is nothing wrong with telling people a "Big surprise" is coming on a certain date. As long as he is not saying something like, "On Friday the 10th I have a Big, battleship-sized surprise that may or may not have airplanes (Kearsarge) to reveal at 11am".
That would be violating NDA.
What Carlito is doing here is generally fine.

You got it!
