On the official Transformers Facebook page they are going to have a vote starting today in the US at 9am EST (so that's roughly 11pm here) for a Decepticon to receive an official toy in 2020. There are just silhouettes but obviously:
Gnaw
Runamuck or Runabout
Needlenose
Shrapnel
The voting only goes for 48 hours, but at least with the voting on FB it seems to be an international vote that Aussies can participate in.
Personally I'm hoping it turns out to be Runamuck. I have Timelines Needlenose and Runabout and my Classicsverse collection really needs a Runamuck in it. And Shrapnel and Gnaw have both had toys in recent years.
