It won't surprise many to hear that TakaraTomy is producing more redecos of their Microns... with five translucent coloured ones coming out soon.

Each is a different mould and a different colour, but are shown to be combined, so could be released as a set (a price of 3,000yen is mentioned, which is about AU$35 - so would be about right for five Microns).
I think it says they are out next month.
