I like the Gen Selects packaging (and it's improved over the last few years). It would never "sell" at a Kmart, but if (and when) we fans order direct from Hasbro rather than through the discount department stores, I'd be happy for all the toys to come in that form of packaging.
Other Hasbro toy lines are going to completely closed boxes (Marvel Legends, the 3.45" Thor movie toys) so kind of expect that Transformers will follow that trend too (already here for Leader, Commander and Titan) but clearly not right away based on the Earthrise reveals. I think for the Earthrise type gimmick toys aimed at the younger audience (all of Earthrise is aimed at not us!) the open packaging that allows the gimmick to be activated/seen makes sense.
