I'm sure some of the less popular colorways and main figures will go to a sold out status but the popular ones will be re-produced again for a time.
They plan to re-inventory and open the store up to be non-preorder and then move to releasing new available blanks and accessory sets in new colors every few weeks.
The ones I know of will be a translucent blue accessory set and an additional GID set that will have all the other pieces not already done.
And we have already seen some of the new colors.
Light blue, green, transparent, and white
