The Wiki is wrong, as it often is. It is updated by the community, not the developers, and should not be considered official information.
Amazon is currently on version 1.2.10333, at least on my device, and that was last updated in September (according to the wiki). You are correct in that Amazon has not received any of the fishing/Duke update yet.
There was no Amazon update on Dec 22, as stated by the Wiki. The last news from 505Games on the update/patch front is this (from Dec 23):
There was nothing released on Dec. 23 for GooglePlay either, as they had hoped.
The certification teams for Apple, Google and Amazon were all shut down before Christmas and won't resume operations before Monday. That was completely out of 505Games' control. Hopefully this coming week will see some progress on getting updates/fixing bugs in users' hands.
