I have a feeling that this is only going to apply to new devices (with the different OS) -
Older devices will be unaffected as the current OS cannot be changed........ (I'm Not and Expert !!!)
==== the following was poste by

"...Plans to roll out the new software may come as early as next year starting with the release of a new Fire TV device.
We don’t expect current Fire TV models to receive this OS update plus they should still support their current lineup with updates for years to come.
Vega is based on Linux OS and uses a “more web-forward application model” with a focus on the React Native software framework.
The biggest thing to note here is that in all likelihood, the Vega OS will eliminate the ability to
sideload apps on Firestick & Fire TV devices.
This would make it a “closed-source” system similar to that of Roku and Apple TV devices which do not have any 3rd party app capabilities.
Fire OS has been very accommodating for app developers in allowing them to run Android Apps that work on phones, tablets, and more.
The integration of Vega to replace Fire OS would also occur on Fire HD Tablets which means these devices would also no longer have access to Android Apps...."
