Can't remember on which thread but already stated that Sideshow's video of their own (Star Wars) productions demonstrates they clearly shift focus on 1:4, 1:2 and 1:1. Moreover, selection across scales is pretty limited with essentially the same characters over and over again.
I'd be interested to here from Premium Format collectors on that matter. It seems to me Sideshow are releasing a new Vader or Boba Fett every other year lately. I get why a manufacturer wouldn't go as deep in a license with such large items. Very few collectors can spare that much space on second tier characters after all. Yet, i feel like Sideshow are really milking it to death with a very limited roaster of characters (Vader, Fett, Stormtrooper, Luke, Han, Chewy, 3PO, R2, rinse and repeat) being updated over short period of times with the eventual new piece here and there (Rey, BB-8, Phasma, Jyn, Deathtrooper).
