I voted only for that which I thought is likely to happen, not for what I want. 'what features will the high-end Kindle HAVE' is the title of the poll.
The only listed features that I would want (and did not vote for) are Liquavista (color) and restoration of audio capabilities for TTS if not other audio applications (speakers not needed provided there's a output jack and ideally, Bluetooth). The latter isn't worth doing unless TTS is improved (more languages/voices, noting that this needs to sell outside English markets, and even there maybe folks would prefer a non-US inflection of English so they can hear proper pronunciation for a change
).
Kindles of yore also had a primitive MP3 player and Audible player. Unless these are greatly improved, no need for that software.
'Bluetooth' connectivity was not listed explicitly, though that is one of the rumored features. Sure, you can pair with Echo, but there are cheaper speaker and headphone options. And it would be nice to be able to use an external keyboard for typing notes and basic navigation without having to touch the screen (the Fire, by the way, has decent keyboard navigation: you can navigate to home screens and select an item to open, turn pages, etc. With a mouse/trackpad, you can also do most of the other stuff).
Echo/Tap/Dot TTS have what I would call 'adequate' TTS but it is no substitute for on-device TTS. Navigation, for example is very basic and can be very frustrating if you want to jump to a different location with voice command (perhaps the Alexa app can be used to navigate to specific chapters, but cannot check that right now). No speed adjustment, and only one voice thus far (US English female).
