Those look fake.
Reason one: just look at the faces, thats an Anakin photo badly photoshopped
Reason two: If we were gonna redo the faces wed remodel the body as well but Lukes body is in the old cartoony style and very low poly, Anakin still has his huge hulk hands. Makes no sense, plus Lucas would never approve that.
Reason three: Models get redone for reasons suck as reworks, use in an event or opportunity. If theyre redoing the First Time User Experience that WOULD give them an excuse to redo the first set of models the player would get, I definitely would push for that, but it would never make it to a build that you can datamine without the rest of the stuff like updated icons (which they did for JKA but not Luke)
Stranger things have happened and I could be wrong but my guess is that this is just somebody trying to get their 15 minutes.
