This set reminds me a lot of GMK Bingsu, in terms of both colors, and the way sales are going, in terms of the set being relatively slept on (Bingsu only sold ~430 base kits before extras, and is very sought after nowadays). I've joined for 1 base kit so far, but if the sales don't improve I might pick up some extra base kits as it's probably going to be a pretty popular set once it ships.
