The following info has just been made available from Gentle Giant courtesy of their Facebook page regarding production changes to the regular edition General Veers mini bust:

The concept for the regular edition of our General Veers Mini Bust changed in development. Originally, the regular edition bust featured General Veers wearing un-removable AT-AT pilot armor. In revising the bust, we decided to display him in his officer’s uniform instead. We failed to keep you updated about the nature of these changes before this piece was released. This was unintentional, and we sincerely apologize for any disappointment and confusion this error has caused. If you are not satisfied with the final product, please return it and we will be happy to issue a full refund.

So, it appears that only PGM Members will be able to get Veers with the interchangeable AT-AT Commander components.
