>>9317200Bandai is probably doing what 30MM doing at the begining, The very first batch was rather generic(or one could say blank) with tons of costumization addons sold separately.
Later they release the blank+new part which have more specified look, then they release new unit and new add-on which have different look and shape from the first batch.
Currently 30MS is at blank+extra part batch.
