It looks like 2017 is the year of the astromech droids as far as LEGO Star Wars polybags are concerned. There has been a new R3-M2 (40268) polybag that’s the traditional minifigure version that’s been found in a Romanian monobrand store. Upon some research, R3-M2 is from Rogue One.
If you look closely, you can see that it’s on it’s own stand and has a plaque card on the back with the name tag appearing to be a sticker. There’s even a Technic pin on the side of the stand that suggests there could be more polybags like this in the future.
I have a feeling that the R3-M2 (40268) will be this year’s May the 4th polybag promotion.
