I saw goatpig's comment in the thread you refer to

> Armory is not for altcoins. I provided a BCH signer so that people can get their coins out. I will provide a BTG signer to the same end.

But I haven't found any info about which release it will be in. 
Is there any info on that?

goatpig:  If I donate could I incentivize you to put it in 0.96.4?
