Takara Tomy's decision to cancel BT-17 Ginrai and BTA-4 Black Convoy seems to indicate a reluctance to further the Binaltech Line. As we know BT Black Widow, the BT counterpart of Decepticharge has been in postponement for months. With that news of 2 cancellations of the Dodge Ram mold and no news from Takara it is becoming unlikely we will see BT Black Widow to be released
I think its safe to say that when Takara doesn't even release the Optimus Prime/Convoy/Ginari of a given line then its thoroughly dead as far as they're concerned. OTOH that doesn't actaully mean that Takara/Tomy won't be involved in the development of futher Alternators, as Hasbro has contracted out sculpting for non-Takara release lines to Takara before.
