They already did it when they renewed the paint line.
It was limited edition and doesnt contain every colour (edge colours were not released at that point)
Seemed like a bit of a waste
tbh, the new line is great, but no one needs every one of those colours... the vast majority are mixes of others and can be made at home, its just convinient to have premixed available for uniform colours.
The storage rack looked handy mind you
