We're already getting a mini figure pack, so I certainly believe so. Here is the checklist of the skins I really want:
-Mariachi Reaper (either)
-Frostbite or Possessed Pharah (I don't know whether or not they'd do seasonal, though)
-Minifigure-sized Baby Winston with Hammond (Please, please, please, please)
-Cruiser D.Va (I have a feeling one minifigure will be her without her mech)
-Any minifig for Reinhardt (You know, without the Crusader suit)
-Summoner Symmetra (One of my favorite skins in the game)
I don't really want a minifigure-scale Roadhog, though they could take a hint from Bombur and make him if they really wanted to.
