The subtext of Solo: A Star Wars Story seems to be that this is clearly Childish Gambino's year.  I don't care what the movie title is, this is the Lando movie and the very first official Donald Glover Lando Calrissian reveal is in the 6-inch action figure line.  It's awesome.   (Are you watching Atlanta?  You should watch that.)  But I digress - the figures will follow the same pattern as usual.  Will new figures slip out early thanks to the same assortment running since 2015?  It's possible!  But here's what Hasbro has to say:
