These just went up for pre-oder and the chatter has been pretty positive on this wave.  Everyone seems to be looking forward to Black Panther.  Others in the set include Captain America, Iron Man (Mark 46), Nick Fury, Red Guardian, and Nuke.  The case break down will give you an extra Iron Man and Captain America.  If you are a fan of hunting these down in the wild, save those for last.  It says they are due out in April but start looking for them in big boxes soon.  We got some high resolution photos from Marvel that let you know who has what body part for the Giant Man BAF.  It is no secret he is in the movie since the Giant Man 6-inch POP! is out and there is a Lego set on shelves with him in it.
