The new Fire TV will begin arriving at customer’s doorsteps with Fire OS 5 on October 5th. I’m told by trusted sources at Amazon that around the same time, existing 1st generation Fire TVs and Fire TV Sticks will receive a software update that will upgrade them to Fire OS 5. Along with this update will be all the Alexa features that will be present on the new Fire TV. Fire TV Stick owners without a voice remote will be able to use the Fire TV Remote App to issue Alexa voice commands.
You have to praise Amazon for bringing Alexa to existing devices. They could have easily made Alexa exclusive to the new Fire TV in order to increase sales. When Apple introduced Siri on the iPhone 4S, they did not add the feature to older devices. It looks like Apple will be repeating history and not updating existing Apple TVs with Siri. Bravo Amazon and Lab126 for continuing to improve the Fire TV month after month, even when the attention is on new hardware.
