I got mine earlier today. White, back lit with MX blues. As promised it has wonderful PBT caps. It also included the non-pastel RBG modifiers in perfect condition. It is wonderful to type on and my new favorite keyboard. Now i just have to get a nice low profile case to really make it great. I'm very pleased!
QWEQThere are some threads on the mechanical reddit and it does look like the keycaps are PBT. Can't confirm without the water test or the break test though.
