>>7573645 said) but rather as a boxed set.
The good news at least is that the improvements in these sets tend to carry over to the next season's toys. The Ex-Aid ones had improved articulation which carried on to Build, Build had interchangeable hands which carried over to Zi-O. With any luck the Zero-One So-Do's will come right out of the gate with translucent eyes and molded soles and shit.
