I'll try and clarify a few things. The eFX Boba Fett helmet is still planned for production, just don't expect to see anything for another year or two. These busts are the result of LFL giving ANOVOS the costume license. Darth Voorhees put it right by saying it in simple terms for this thread, Anovos makes costumes and eFX makes prop replicas.
eFX had acquired several pieces and means to go about making a full biker scout but LFL told them to cease those plans. eFX had done a lot of leg work to go about finding some means and materials to put towards full sized costumes and I feel that these busts are their way of putting those items to use.
The rumor that KenChen posted is false.
